BSS138BK-TP

MCC Micro Commercial Components · MOSFETs · SOT-23

BSS138BK-TP from MCC Micro Commercial Components, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 GATE input Gate; gate-source voltage limited to ±20 V, with ESD protection up to 2 kV HBM and threshold of 0.5 V to 1.5 V at ID=250 µA.
2 SOURCE passive Source terminal of the N-channel MOSFET; continuous body diode current is 0.5 A.
3 DRAIN passive Drain; drain-source voltage rated 50 V and continuous drain current 0.59 A.
