BLM2301

BL Shanghai Belling · MOSFETs · SOT-23

BLM2301 from BL Shanghai Belling, 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 limit is ±12 V, threshold VGS(th) -0.4 to -1 V, and the device operates with gate voltages as low as 2.5 V.
2 S passive Source of the P-channel MOSFET; the body diode forward current is limited to -1.3 A.
3 D passive Drain; drain-source voltage is limited to -20 V, continuous drain current to -3 A and pulsed drain current to -10 A.
