TPESD203-B1-02EL 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 | Terminal 1 (bidirectional TVS) | passive | One of two terminals of the bidirectional TVS diode, shown on the terminal connection diagram as pin 1 at the top of the symbol; the part's reverse working voltage is 13.2 V max and clamping voltage is 20 V max at IPP = 6 A (8x20 µs). |
| 2 | Terminal 2 (bidirectional TVS) | passive | The other terminal of the bidirectional TVS diode, shown as pin 2 at the bottom of the symbol; the same bidirectional clamp applies in both polarities, with ESD immunity of ±30 kV air and contact per IEC 61000-4-2. |
