BZT52C3V6S

Changjing · Zener Diodes · SOD-323

BZT52C3V6S from Changjing, in a SOD-323. 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 banded end marked "-" on the SOD-323 drawing; the zener voltage is 3.4 V min to 3.8 V max at IZT = 5 mA for the BZT52C3V6S.
2 A passive Anode, the lead marked "+" on the SOD-323 drawing; the maximum forward voltage is 0.9 V at IF = 10 mA, with 200 mW power dissipation.
