HSM15.TCT 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 line 1 (cathode of one TVS diode in the circuit diagram); working voltage 15V, can protect one bidirectional line with pin 2 or be used as a unidirectional line. |
| 2 | I/O2 | passive | Protected line 2 (cathode of the second TVS diode in the circuit diagram); working voltage 15V, can protect one bidirectional line with pin 1 or be used as a unidirectional line. |
| 3 | COMMON | passive | Common node joining the anodes of both diodes in the circuit diagram, typically tied to ground for unidirectional protection. |
