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

TPESD5311N 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 | IO1 | passive | One of the two terminals of the single-line TVS diode array, shown in the Pin Configuration diagram as the top terminal of the back-to-back diode symbol; the datasheet gives a reverse working voltage of 5 V max and 0.18 pF typical (0.25 pF max) junction capacitance IO to IO. |
| 2 | IO2 | passive | The other terminal of the single-line TVS diode array, shown as the bottom terminal of the back-to-back diode symbol; the datasheet gives a breakdown voltage of 6 V min and 9 V max at IT = 1 mA, with clamping voltage of 12 V max at IPP = 1 A (8/20 µs). |
