BS270

onsemi · MOSFETs · TO-92

BS270 from onsemi, in a TO-92. 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 D passive Drain of the N-channel MOSFET, rated 60 V drain-source (VDSS) and 400 mA continuous (2000 mA pulsed) drain current.
2 G input Gate, rated ±20 V continuous (±40 V non-repetitive, tp < 50 µs) gate-source, with a 1 V to 2.5 V threshold at ID = 250 µA.
3 S passive Source of the N-channel MOSFET, which is the reference terminal for the VGS and VDS ratings.
