BSS138WH6327XTSA1 MOSFET Specifications Applications and Suppliers

ElecSuppliers Part Number GuideAug 15, 2026

BSS138WH6327XTSA1 is an N channel MOSFET from Infineon designed for low voltage switching and signal control applications.

The BSS138 family is widely used in compact electronic circuits where a small MOSFET is needed to control or switch signals and low current loads. The complete part number identifies a specific device and ordering configuration, so it should be retained when sourcing the component.

BSS138WH6327XTSA1 MOSFET Characteristics

A MOSFET is a voltage controlled semiconductor device. Unlike a bipolar transistor, the gate primarily controls the current flowing between the drain and source.

For BSS138WH6327XTSA1, engineers should evaluate parameters such as drain source voltage, continuous drain current, gate threshold voltage and on resistance when determining whether it is suitable for a particular circuit.

The gate threshold voltage should not be confused with the voltage required to achieve low on resistance. The actual gate drive conditions need to be considered when designing the switching circuit.

BSS138WH6327XTSA1 Switching Applications

BSS138WH6327XTSA1 can be used in low voltage switching circuits where a compact N channel MOSFET is required.

Possible applications include signal switching, logic level control, load switching and interface circuits.

It can also be used in circuits where a small MOSFET is needed to translate or control signals between different parts of an electronic system.

The actual load current and voltage should remain within the device's specified operating limits.

BSS138WH6327XTSA1 for Signal Level Translation

One common use for small MOSFETs in the BSS138 family is bidirectional signal level translation.

A MOSFET based level shifting circuit can allow signals between devices operating at different logic voltages to communicate while providing a simple hardware implementation.

This can be useful in embedded systems that combine different voltage domains.

The exact circuit configuration and pull up resistors depend on the interface and communication speed being used.

BSS138WH6327XTSA1 Package

The package is an important consideration when using BSS138WH6327XTSA1 in a PCB design.

Its compact surface mount format is suitable for space constrained electronic products, but engineers should verify the exact package dimensions, pin configuration and recommended land pattern before creating the PCB footprint.

When replacing another BSS138 device, package compatibility should be confirmed rather than assumed from the family name alone.

BSS138WH6327XTSA1 Selection Considerations

When choosing BSS138WH6327XTSA1, the most important parameters depend on the intended circuit.

For switching applications, on resistance and gate drive voltage can have a direct impact on conduction losses.

For signal applications, leakage, capacitance and switching behavior may be more important.

Temperature should also be considered because semiconductor characteristics can change as the operating temperature increases.

BSS138WH6327XTSA1 Supplier Information

When searching for BSS138WH6327XTSA1 suppliers, buyers should use the complete manufacturer part number.

The manufacturer, MOSFET configuration, voltage rating, current rating, package and product status should be checked against the original BOM.

Another BSS138 variant may have similar electrical characteristics but a different package or ordering configuration, so the exact MPN remains important for production sourcing.
