TPE4V5KHC from TECH PUBLIC, in a SOD-323. 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 two terminals of the 1-line bidirectional diode, which protects one data or power line, rated at 4.5 V reverse working voltage and 2500 W peak pulse power (8/20 µs). |
| 2 | 2 | passive | The other terminal of the 1-line bidirectional diode, which protects one data or power line, rated at 4.5 V reverse working voltage and 2500 W peak pulse power (8/20 µs). |
