SMBJ13A-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 | K | passive | Cathode terminal, marked by the cathode band on unidirectional types (SMBJ13A-TR is unidirectional); the datasheet states a 13 V stand-off voltage (VRM) and 14.4 V min to 15.2 V max breakdown voltage at 1 mA. |
| 2 | A | passive | Anode terminal; the device clamps at 21.5 V max at 29 A (10/1000 µs) and is rated for 600 W peak pulse power (10/1000 µs). |
