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

TPESD8D5.0CT5G 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 | Terminal 1 of the 1-line bidirectional TVS diode, shown as one of two symmetric terminals in the datasheet terminal diagram, with a reverse working voltage (VRWM) of 5 V maximum and a breakdown voltage (VBR) of 5.6 V to 8.4 V at 1 mA. |
| 2 | 2 | passive | Terminal 2 of the 1-line bidirectional TVS diode, shown as the opposite symmetric terminal in the datasheet terminal diagram, with the same bidirectional clamping behaviour (clamping voltage 10 V at 8 A, 8x20 µs pulse). |
