BSS123LT1G MOSFET Specifications Applications and Suppliers

ElecSuppliers Part Number GuideAug 15, 2026

BSS123LT1G is an N channel MOSFET used in low power switching applications. The device is commonly considered for circuits that require a compact transistor for controlling signals or relatively small loads.

For engineers and purchasing teams searching for this specific component the complete BSS123LT1G part number is important because the BSS123 family includes related products with different manufacturers packages and ordering codes.

BSS123LT1G Key Characteristics

BSS123LT1G is designed as a small signal N channel MOSFET. When evaluating the component the main parameters include drain source voltage drain current gate source voltage and drain source on resistance.

Gate drive conditions are also important. The actual on resistance depends on the gate source voltage used in the circuit so the specification should be evaluated under conditions that are relevant to the intended application.

The maximum power dissipation and operating temperature should also be considered when the device is used continuously or in a compact PCB design.

Where Is BSS123LT1G Used

BSS123LT1G can be used for low power switching and signal control in electronic circuits.

Typical applications can include load switching interface circuits digital control circuits signal switching and portable electronic equipment.

Its small signal characteristics make it more suitable for low power switching functions than applications requiring a high current power MOSFET.

BSS123LT1G Package Information

The package is an important part of identifying BSS123LT1G.

When designing or repairing a PCB the physical dimensions terminal arrangement and recommended PCB footprint should be checked before using the component.

This becomes especially important when comparing BSS123LT1G with another BSS123 device. Similar part numbers do not automatically guarantee the same mechanical configuration.

BSS123LT1G Supplier Information

When sourcing BSS123LT1G buyers should use the complete manufacturer part number when requesting quotations.

The manufacturer package electrical specifications product status and required quantity should be confirmed before an order is placed.

For production purchasing it is also useful to verify whether the supplier can provide the exact part number consistently rather than supplying a different BSS123 variant.

BSS123LT1G for BOM Sourcing

If BSS123LT1G appears on an electronic BOM the exact MPN should be retained during the sourcing process.

Searching for the complete BSS123LT1G designation helps narrow the results to the required component and reduces confusion with other N channel MOSFETs that may have similar electrical characteristics.
