BZT52C15S-WJ

SY(顺烨) · IC · SOD-323

BZT52C15S-WJ from SY(顺烨), 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, marked by the cathode bar on the SOD-323 body; goes positive of anode in Zener breakdown, with nominal VZ of 15 V (13.8 V to 15.6 V) at IZT = 5 mA.
2 A passive Anode, the end opposite the cathode bar; forward voltage is 0.9 V at IF = 10 mA, with PD of 200 mW and Tj of 150 ℃ maximum.
