**TECH PUBLIC** · ESD Protection Devices · SOT-23-3

TPPESD5V0L2BT from TECH PUBLIC, in a SOT-23-3. 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 | Protected line 1 of the 2-line bi-directional TVS diode, with reverse working voltage 5 V max and clamping voltage 10 V max at Ipp=9 A (8/20 µs). |
| 2 | IO2 | passive | Protected line 2 of the 2-line bi-directional TVS diode, with reverse working voltage 5 V max and clamping voltage 10 V max at Ipp=9 A (8/20 µs). |
| 3 | COMMON | passive | Common node shared by both TVS channels, with junction capacitance 15 pF typ and 20 pF max measured from pin 1 or pin 2 to pin 3. |
