BZT52C12T-TP from MCC(美微科), in a SOD-523. 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 cathode band; Zener voltage 12 V nominal (11.4 V to 12.7 V) at IZT = 5 mA for BZT52C12T. |
| 2 | A | passive | Anode, the end opposite the cathode mark; maximum forward voltage is 0.9 V at IF = 10 mA. |
