BZT52C13-WI

SY(顺烨) · IC · SOD-123

BZT52C13-WI from SY(顺烨), 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 by the cathode bar on the body; for BZT52C13 the zener voltage is 12.4V min to 14.1V max at IZT=5mA.
2 A passive Anode, the terminal opposite the cathode bar; total power dissipation is max 500mW and forward voltage is 0.9V at IF=10mA.
