**Diodes Incorporated** · Zener Diodes · SOD-523

BZT52C13TQ-7-F from Diodes Incorporated, 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 terminal, identified by the cathode band on the package; goes positive relative to the anode in Zener breakdown (VZ 12.4V min to 14.1V max at IZT 5mA for the 13V nominal type). |
| 2 | A | passive | Anode terminal, the end opposite the cathode band; forward voltage is 0.9V at IF = 10mA. |
