Single FETs, MOSFETs Procurement Notes

Verify the specific suffix W indicates the SOT-323-3 package configuration distinct from other BSS138 variants. Confirm RoHS compliance status through official manufacturer documentation prior to finalizing procurement orders. Ensure the ordering part number matches the required package type for the intended PCB layout design.

Single FETs, MOSFETs Selection Notes

Select this component when a small signal N-channel MOSFET is required in a SOT-323-3 footprint. The 50V rating and 220mA current capacity suit low-power switching tasks. Consider the 3.5 Ohm on-resistance for efficiency calculations in gate driver or low-current load applications where space constraints necessitate this specific package size.

Single FETs, MOSFETs Part Context

This component belongs to the BSS138 family of small-signal MOSFETs produced by Micro Commercial Components. While sharing core electrical characteristics with industry-standard BSS138 devices, the BSS138W-TP variant specifically denotes the SOT-323-3 package form factor. This distinguishes it from other package options like SOT-23 available within the broader product line.

Single FETs, MOSFETs Replacement Considerations

Cross-reference with generic BSS138 parts in SOT-323-3 packages. Verify pinout compatibility and ensure replacement devices meet the 50V Vds and 220mA Id specifications. Check that alternative manufacturers offer equivalent thermal performance and switching characteristics for direct substitution.
