BSS138L

ElecSuper · MOSFETs · SOT-23

BSS138L from ElecSuper, 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 of the N-channel MOSFET, with gate-source voltage VGS rated ±20 V (absolute maximum).
2 Source passive Source of the N-channel MOSFET; the body diode forward voltage is specified as VSD 0.86 V typical (1.5 V max) at VGS=0 V and IS=0.5 A.
3 Drain passive Drain of the N-channel MOSFET, rated for a drain-source voltage BVDSS of 60 V and a continuous drain current ID of 0.40 A at TA = 25 ℃.
