BZT52C27-WP

SY(顺烨) · IC · SOD-123

BZT52C27-WP 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, the terminal marked with the cathode bar on the body; it goes positive in zener reverse breakdown (VZ 25.1V min, 27V nom, 28.9V max at IZT=2.5mA for the C27).
2 A passive Anode, the terminal opposite the cathode bar; forward voltage is 0.9V at IF=10mA and power dissipation is max 500mW.
