SMBJ58CA-TR from STMicroelectronics, in a SMB(DO-214AA). 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 | A1 | passive | Bidirectional TVS terminal 1 (SMBJ58CA, VRM 58 V, VBR 64.4 to 67.8 V at 1 mA), interchangeable with the other terminal since the device clamps in both polarities. |
| 2 | A2 | passive | Bidirectional TVS terminal 2 (SMBJ58CA, VRM 58 V, max VCL 93.6 V at 6.7 A for 10/1000 µs), interchangeable with the other terminal since the device clamps in both polarities. |
