Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | PIN 1 | passive | Terminal 1 of the unidirectional WS58P6SMB TVS (VRWM 58 V, VBR 64.4-71.2 V at 1 mA, Vc 93.6 V at 6.4 A Ipp); the cathode band marks the cathode terminal on unidirectional parts. |
| 2 | PIN 2 | passive | Terminal 2 of the unidirectional WS58P6SMB TVS (600 W peak pulse power at 10/1000 µs, max leakage 1 µA at 58 V); the cathode band marks the cathode terminal on unidirectional parts. |
