BS870Q-7-F

Diodes Incorporated · MOSFETs · SOT-23

BS870Q-7-F from Diodes Incorporated, 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 G input Gate; gate-source voltage limited to ±20 V with threshold VGS(TH) of 1.0 V min to 3.0 V max at ID = 250 µA.
2 S passive Source terminal of the N-channel MOSFET, the reference for VGS and VDS.
3 D passive Drain; drain-source voltage rated 60 V with 250 mA continuous drain current and RDS(ON) of 5 Ω max at VGS = 10 V.
