HSM24-02HTG 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 connected through a TVS diode to common pin 3, for 24V working voltage (VRWM) with 26.7V min breakdown at 1mA. |
| 2 | I/O2 | passive | Protected line 2 connected through a TVS diode to common pin 3, for 24V working voltage (VRWM) with 26.7V min breakdown at 1mA. |
| 3 | COMMON | passive | Common node shared by both TVS diodes, used as the second terminal when protecting one bidirectional line between pins 1 and 2 or as the reference for two unidirectional lines. |
