# HPSOT15C-LF-T7

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

HPSOT15C-LF-T7 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 (one diode to common pin 3); protects a bidirectional line together with pin 2 or acts as one of two unidirectional lines, 15V working voltage. |
| 2 | I/O2 | passive | Protected line 2 (second diode to common pin 3); acts as the second unidirectional line, 15V working voltage. |
| 3 | COMMON | passive | Common node of the two protection diodes shown in the circuit diagram, typically connected to ground for unidirectional protection. |

## CAD (KiCad official)

- Symbol: `HPSOT15C-LF-T7`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `hpsot15c-lf-t7-etched.step` / `hpsot15c-lf-t7-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `hpsot15c-lf-t7.step` / `hpsot15c-lf-t7.glb` are the bare package body.
