VN920DB5TR-E High-Side Driver Specifications and Applications

ElecSuppliers Part Number GuideSep 25, 2026

VN920DB5TR-E is the tape-and-reel ordering version associated with the VN920D-B5 high-side driver from STMicroelectronics. The device is part of the STMicroelectronics VIPower M0-3 family and is designed to control electrical loads with one side connected to ground.

The VN920D-B5 is a monolithic high-side driver that combines power switching with integrated protection functions. It is designed for applications where a controlled high-side output is required while protection against overload and abnormal operating conditions is also important. STMicroelectronics specifies a 36 V supply rating and a 30 A output current rating for the device, with an RDS(on) specification of 18 mΩ.

VN920DB5TR-E Specifications

The VN920D-B5 device provides a single high-side output and is designed for switching loads connected between the output and ground. Its electrical characteristics make it suitable for automotive and other 12 V and 24 V electrical systems.

Key specifications include a 36 V supply voltage rating, 30 A output current capability and 18 mΩ RDS(on). The device also uses a CMOS-compatible input, allowing it to be controlled by a suitable digital control circuit.

The device incorporates several diagnostic and protection functions. These include on-state and off-state open-load detection, shorted-load protection, under-voltage and over-voltage shutdown, overvoltage clamping and protection against loss of ground.

VN920DB5TR-E High-Side Driver Operation

A high-side driver controls the positive side of an electrical load. In a typical circuit, the load is connected between the driver output and ground, while the VN920D-B5 controls the connection between the power supply and the load.

This arrangement is useful in systems where loads share a common ground and individual loads need to be switched from the positive supply rail.

The integrated power stage eliminates the need to build the complete switching function from a separate controller and discrete power transistor. Protection functions are also integrated into the device, which can simplify the design of load-control circuits.

VN920DB5TR-E Protection Features

Protection is an important part of the VN920DB5TR-E design. STMicroelectronics specifies active current limitation combined with thermal shutdown and automatic restart to protect the device against overload conditions.

The device also provides shorted-load protection and voltage protection functions. Under-voltage and over-voltage shutdown help prevent operation outside the intended supply conditions, while the overvoltage clamp provides protection against certain low-energy voltage spikes.

Open-load detection is available in both the on-state and off-state. This provides additional diagnostic information for systems that need to detect whether the controlled load is connected correctly.

The device also provides protection against loss of ground. These features are particularly relevant to automotive electrical systems where electrical transients and abnormal wiring conditions need to be considered during system design.

VN920DB5TR-E Package Options

The VN920D-B5 is available in a P²PAK package, while the related VN920DSO version uses an SO-16L package. STMicroelectronics lists VN920D-B5 as the P²PAK version and identifies VN920DB513TR as its tape-and-reel order code in the official device documentation.

When sourcing VN920DB5TR-E or evaluating a related VN920D-B5 device, package information should be checked carefully. The package affects PCB layout, thermal management and mechanical compatibility.

For replacement applications, buyers and engineers should verify the complete ordering code rather than matching only the base VN920D-B5 designation.

VN920DB5TR-E Applications

The VN920D-B5 is intended to drive different types of loads with one side connected to ground. Its high-side configuration and integrated protection functions make it suitable for applications requiring controlled power distribution and load switching.

Automotive Load Control

High-side drivers are widely used in vehicle electrical systems to control loads from a battery supply. The protection and diagnostic functions of the VN920D-B5 are useful when the switching device must operate under variable electrical conditions.

Power Distribution

The device can be used for controlled distribution of power to individual loads. A system can use separate high-side outputs to switch different loads while maintaining a common ground reference.

Industrial Control

The device can also be considered for certain industrial control applications that use low-voltage DC power systems. The suitability of the device depends on the required load current, voltage range, thermal conditions and switching characteristics.

Actuator and Solenoid Control

High-side drivers can be used to control actuators, solenoids and other electrical loads. When using the VN920D-B5 with inductive loads, the complete switching circuit should be evaluated to ensure that voltage transients, load current and thermal conditions remain within the specified operating limits.

VN920DB5TR-E Design Considerations

The 30 A output rating should not be interpreted as a universal operating current under every application condition. Actual performance depends on factors such as ambient temperature, PCB thermal characteristics, load type, duty cycle and operating conditions.

The 18 mΩ RDS(on) value is also relevant when estimating conduction losses. As current increases, power dissipation in the output stage increases, so thermal design becomes increasingly important for high-current applications.

PCB copper area and thermal paths should therefore be considered when designing around the device. The package and board layout need to provide an appropriate path for dissipating heat generated during operation.

For inductive loads, engineers should also evaluate the complete load switching behavior and transient conditions rather than relying only on the nominal output current specification.

VN920DB5TR-E Sourcing Considerations

The exact part number should be confirmed when purchasing VN920DB5TR-E. STMicroelectronics documentation distinguishes between the VN920D-B5 base device and its ordering codes. The official datasheet identifies the P²PAK version as VN920D-B5 and the tape-and-reel ordering code as VN920DB513TR.

The current STMicroelectronics product page identifies VN920B5-E as obsolete and out of production, so buyers looking for VN920DB5TR-E or related VN920D-B5 devices should verify current availability and product status before placing a production order.

When requesting a quotation, buyers should provide the complete part number, required quantity, package requirement and delivery location. For older or obsolete components, additional verification of date code, packaging condition, traceability and available stock may also be appropriate.

VN920DB5TR-E for Electronic Component Procurement

VN920DB5TR-E belongs to a family of integrated high-side power switches designed for controlled load switching. Its combination of a high-current output stage, low on-resistance and integrated protection functions makes the VN920D-B5 relevant to automotive load control and other DC power switching applications.

For engineers evaluating the device, the key parameters include output current, supply voltage, RDS(on), protection functions, package configuration and thermal performance. For buyers, confirming the exact ordering code and current availability is particularly important because the related VN920B5-E and VN920D-B5 products are older STMicroelectronics devices.

Buyers sourcing VN920DB5TR-E can compare available electronic component suppliers and request quotations based on quantity, package requirements and delivery requirements.
