HSS3402A from HUASHUO, 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 channel, with VGS rated ±12 V maximum and threshold VGS(th) of 0.5 V min, 1 V typ and 1.6 V max. |
| 2 | S | passive | Source; the body diode is rated for continuous source current IS of 4 A and pulsed 16 A. |
| 3 | D | passive | Drain; VDS is rated 30 V maximum and continuous drain current is 4 A at TA=25℃ (pulsed 16 A). |
