GME(银河微电) · MOSFETs · SOT-23
BL3401 from GME(银河微电), 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; controls the P-channel MOSFET, with VGS limited to ±12 V and threshold VGS(TH) of -0.7 to -1.3 V at ID = -250uA. |
| 2 | S | passive | Source; current path terminal of the P-channel MOSFET, with body diode forward voltage of -1 V max at ID = -1A. |
| 3 | D | passive | Drain; VDSS of -30 V, continuous ID of -4.2 A and pulsed IDM of -16 A. |
