HL3402 from hongjiacheng, 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 of the N-channel MOSFET; gate-source voltage is rated at ±12 V (VGS) with a 0.65 V to 1.5 V threshold. |
| 2 | S | passive | Source of the N-channel MOSFET, the reference for the gate-source voltage; the device is rated 30 V VDS. |
| 3 | D | passive | Drain of the N-channel MOSFET, rated 30 V VDS with 2.5 A continuous drain current at TA=25℃ and 16 A pulsed drain current. |
