TPPESD5V0S1BB from TECH PUBLIC, in a SOD-523. 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 | TVS terminal 1 | passive | One terminal of the bidirectional TVS clamp for a data or power line, rated for a 5 V maximum reverse working voltage (VRWM) with 200 nA maximum reverse leakage at 5 V and 6 V minimum / 9 V maximum breakdown at IT = 1 mA. |
| 2 | TVS terminal 2 | passive | The other terminal of the bidirectional TVS clamp, with 7 V maximum clamping voltage at IPP = 1 A (8x20 µs) and 9 V maximum at IPP = 7 A (8x20 µs). |
