TV02W430B-HF from Comchip, in a SOD-123. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | A1 | passive | Anode/terminal 1 of the bidirectional TVS. Non-polarized on bidirectional variants (suffix 'B'); polarity is symmetric so either end may connect to the protected line or ground. Working peak reverse voltage 43V, breakdown 47.8-52.8V at IT=1mA. |
| 2 | A2 | passive | Anode/terminal 2 of the bidirectional TVS. Non-polarized on bidirectional variants; symmetric clamping in both polarities. Clamping voltage VC(max) = 69.4V at IPP = 2.88A (10/1000µs). |
