SMBJ12A-TP from MCC(Micro Commercial Components), 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, the end marked with the color band (positive end) on the unidirectional SMBJ12A, which has VWM 12 V, VBR 13.3 to 14.7 V at 1 mA and maximum clamping voltage 19.9 V at IPP 30.2 A. |
| 2 | A | passive | Anode, the unmarked end opposite the cathode band of the unidirectional SMBJ12A, which is rated for 600 W peak pulse power on a 10/1000 us waveform. |
