BSS138W-TP

MCC(Micro Commercial Components) · MOSFETs · SOT-323

BSS138W-TP from MCC(Micro Commercial Components), in a SOT-323. 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 a maximum gate-source voltage of ±20 V and a threshold of 0.8 V min to 1.50 V max at ID=1 mA.
2 SOURCE passive Source of the N-channel MOSFET, with a body diode to drain and a maximum continuous drain current of 0.22 A.
3 DRAIN passive Drain of the N-channel MOSFET, with a maximum drain-source voltage of 50 V and a maximum RDS(on) of 3.5 ohm at VGS=10 V, ID=0.22 A.
