8.0SMDJ58A from Littelfuse, in a DO-214AB(SMCJ). 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 | Cathode | passive | Cathode terminal, marked by the color band on unidirectional parts; for 8.0SMDJ58A the reverse stand-off voltage VR is 58 V and the breakdown voltage VBR is 64.4 V min to 71.2 V max at 1 mA. |
| 2 | Anode | passive | Anode terminal of the unidirectional 8.0SMDJ58A, with a maximum clamping voltage of 93.6 V at 85.5 A peak pulse current (10/1000μs). |
