SM712-HXY from HXY MOSFET, 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 | 1 | passive | One of the two terminals of the bidirectional ESD protection diode, with a reverse working voltage of 12.0 V max (Pin1 or 2 to Pin3), breakdown of 13.5-16.0 V at 1 mA, and clamping of 18.5-20.0 V at 15 A (8/20 µs). |
| 2 | 2 | passive | The second terminal referenced with Pin 1 in the datasheet ratings, sharing the same 12.0 V max reverse working voltage and 13.5-16.0 V breakdown limits (Pin1 or 2 to Pin3). |
| 3 | 3 | passive | The common terminal of the protection diode, with a reverse working voltage of 7.0 V max (Pin3 to Pin1 or 2), breakdown of 7.5-9.5 V at 1 mA, and clamping of 12.5-14.0 V at 18 A (8/20 µs). |
