PSOT03C-LF-T7 from ProTek Devices, in a SOT-23. 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 the two TVS line terminals of the bidirectional PSOT03C, with per-line limits of 3.3 V rated stand-off, 4.0 V minimum breakdown at 1 mA, and 10.9 V clamping at 43 A (8/20 µs). |
| 2 | 2 | passive | One of the two TVS line terminals of the bidirectional PSOT03C, with per-line limits of 3.3 V rated stand-off, 4.0 V minimum breakdown at 1 mA, and 10.9 V clamping at 43 A (8/20 µs). |
| 3 | 3 | passive | Third SOT-23 terminal of the TVS array; the datasheet designates pin 3 as the cathode for unidirectional devices only, so its role on the bidirectional PSOT03C is not stated. |
