# HDUP2105SOQ-7

**HXY MOSFET** · Electrostatic And Surge Protection (TVS/ESD) · SOT-23

HDUP2105SOQ-7 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 with a working voltage of 24 V max (VRWM, pin 1 or 2 to pin 3), connected through its diode to common pin 3. |
| 2 | I/O2 | passive | Protected line 2 with a working voltage of 24 V max (VRWM, pin 1 or 2 to pin 3), connected through its diode to common pin 3. |
| 3 | COMMON | passive | Common pin shared by both diodes, the reference for all electrical characteristics measured from pin 1 or 2 to pin 3. |
