SMBJ58D-M3 from Vishay Intertech, in a DO-214AA(SMBJ). 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 | K | passive | Cathode, marked by the cathode band on the unidirectional SMBJ58D; stand-off voltage VWM is 58 V, breakdown VBR is 65.4 V to 70.2 V at 1.0 mA, and clamping voltage is 92.3 V at 6.50 A IPPM. |
| 2 | A | passive | Anode, the end without the cathode band; the device conducts as a TVS when the cathode is positive relative to it, with 600 W peak pulse power (10/1000 μs). |
