# TPE5302F

**TECH PUBLIC** · ESD Protection Devices · SOT-23

TPE5302F from TECH PUBLIC, 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 | ESD-protected I/O line 1, steered by the diode array to GND (pin 3), with 0.5pF typ (0.6pF max) capacitance to GND and 0.35pF typ to the other I/O. |
| 2 | I/O2 | passive | ESD-protected I/O line 2, steered by the diode array to GND (pin 3), with 0.5pF typ (0.6pF max) capacitance to GND and 0.35pF typ to the other I/O. |
| 3 | GND | power_in | Ground reference, the common node of the TVS diode array; reverse working voltage is 5V max (VRWM) and breakdown voltage is 6.5V min to 9V max at 1mA. |

## CAD (KiCad official)

- Symbol: `TPE5302F`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `tpe5302f-etched.step` / `tpe5302f-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tpe5302f.step` / `tpe5302f.glb` are the bare package body.
