Ensure the ordering part number matches the exact electrical specifications required for the target application. Cross-reference datasheet revisions to confirm package outline dimensions and thermal characteristics before finalizing procurement.

Single FETs, MOSFETs Selection Notes

Select this component when a compact N-channel MOSFET with 50V capability is required for low-current signal or power switching. Compare the 6 Ω on-resistance limit against circuit efficiency requirements. Verify that the SOT-23-3 package fits the PCB layout constraints and that the 350 mW power dissipation rating meets the thermal design needs of the enclosure.

Single FETs, MOSFETs Part Context

This part belongs to the BSS138 series of small signal field-effect transistors produced by Micro Commercial Components. The series is designed for general-purpose switching tasks where space is limited. The BSS138A variant typically denotes specific binning or performance tolerances compared to the base BSS138 model, while the TP suffix indicates tape and reel packaging options available from the manufacturer.

Single FETs, MOSFETs Replacement Considerations

Direct substitutes include BSS138-TP and BSS138A-TP from Micro Commercial Components. Other manufacturers' BSS138 equivalents may be considered if pinout compatibility and electrical parameters such as VDS, ID, and RDS(on) are verified to match or exceed the original specifications.
