BZT52C12-WH-SOD-123

SY(顺烨) · IC · SOD-123

BZT52C12-WH-SOD-123 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; it goes positive in zener reverse breakdown, with total power dissipation limited to 500 mW.
2 A passive Anode, the terminal opposite the cathode bar; forward voltage is 0.9 V at IF=10 mA.
