# HSZESD9101P2T5G

**HXY MOSFET** · ESD And Surge Protection (TVS/ESD) · SOD-923

HSZESD9101P2T5G from HXY MOSFET, in a SOD-923. 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 | K | passive | Cathode of the unidirectional ESD protection diode, connected to the protected line (5 V stand-off voltage VRWM, 0.35 pF capacitance). |
| 2 | A | passive | Anode of the unidirectional ESD protection diode, normally connected to ground (IEC61000-4-2 ±15 kV air, ±10 kV contact). |
