CBI · MOSFETs · SOT-23
BC3400 from CBI, 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 | GATE | input | Gate terminal of the N-channel MOSFET, with gate-source voltage VGS rated at ±12 V. |
| 2 | SOURCE | passive | Source terminal of the N-channel MOSFET, the reference for VGS and for the source-drain diode forward voltage VSD (IS = 1 A, VGS = 0 V). |
| 3 | DRAIN | passive | Drain terminal of the N-channel MOSFET, rated for drain-source voltage VDS of 30 V and continuous drain current ID of 5.8 A. |
