HXY MOSFET · Electrostatic And Surge Protection (TVS/ESD) · SOT-23
HSM24.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 | 1 | passive | Protected line terminal (diode anode in the circuit diagram) for one of two unidirectional lines, with 24V maximum reverse working voltage. |
| 2 | 2 | passive | Protected line terminal (diode anode in the circuit diagram) for the second unidirectional line, with 24V maximum reverse working voltage. |
| 3 | 3 | passive | Common terminal (shared cathode node in the circuit diagram) of the two diodes, used as the return side of the protection. |
