BZT52C13-E3-08 from Vishay Intertech, in a SOD-123. 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 (marked with cathode bar/mark); the Zener diode BZT52C13 has VZ 12.40 to 13.65 V (13 V typ.) at IZT1 = 5 mA, with reverse polarity connection to the positive side in Zener operation. |
| 2 | A | passive | Anode of the single Zener diode; BZT52C13 admissible Zener current is 29 mA at Tamb = 45 °C and 34 mA at Tamb = 25 °C, power dissipation max. 500 mW (300 mW on FR-4 board). |
