GOFORD · MOSFETs · SOT-23-3L
3400L-B from GOFORD, in a SOT-23-3L. 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 of the N-channel MOSFET, usable with gate voltages as low as 2.5V and rated at ±12V maximum VGS. |
| 2 | S | passive | Source of the N-channel MOSFET; the drain-source diode forward current is rated at 2.9A maximum. |
| 3 | D | passive | Drain of the N-channel MOSFET, rated at 25V maximum VDS and 5.8A continuous ID (30A pulsed). |
