HGSOT36C-HG3-18 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 | I/O1 | passive | Protected unidirectional line 1 (diode cathode in the circuit diagram), 36V reverse working voltage, ±30kV IEC 61000-4-2 ESD. |
| 2 | I/O2 | passive | Protected unidirectional line 2 (diode cathode in the circuit diagram), 36V reverse working voltage, ±30kV IEC 61000-4-2 ESD. |
| 3 | GND | power_in | Common anode of both TVS diodes, connected to ground as the return for the two protected lines. |
