# ESDA05CP

**TECH PUBLIC** · ESD Protection Devices · DFN1006-2

ESDA05CP from TECH PUBLIC, in a DFN1006-2. 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 | One of the two identical terminals of the bidirectional TVS diode (pin 1 at top of the terminal connection diagram), with reverse working voltage VRWM of 5 V max and breakdown voltage VBR of 5.6 V min at IT = 1 mA. |
| 2 | 2 | passive | The other of the two identical terminals of the bidirectional TVS diode (pin 2 at bottom of the terminal connection diagram), with reverse working voltage VRWM of 5 V max and breakdown voltage VBR of 5.6 V min at IT = 1 mA. |

## CAD (KiCad official)

- Symbol: `ESDA05CP`
- Footprint: `Diode_SMD:D_SOD-882`
- 3D model: DFN1006-2 (KiCad packages3D, STEP)
- 3D model files: `esda05cp-etched.step` / `esda05cp-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `esda05cp.step` / `esda05cp.glb` are the bare package body.
