SI3400A-TP from MCC Micro Commercial Components, 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 of the N-channel enhancement MOSFET, rated for a gate-source voltage VGS of ±12 V. |
| 2 | SOURCE | passive | Source of the N-channel enhancement MOSFET; the datasheet gives no separate pin-level electrical limit for this terminal. |
| 3 | DRAIN | passive | Drain of the N-channel enhancement MOSFET, rated for a drain-source voltage VDS of 30 V and a continuous drain current ID of 5.8 A. |
