CZRF52C5V6

Comchip · Zener Diodes · SOD-323F

CZRF52C5V6 from Comchip, in a SOD-323F. 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 of the zener diode, marked by the cathode band; the CZRF52C5V6-HF has Vz 5.32 to 5.88 V at IZ = 5 mA and 350 mW maximum power dissipation.
2 A passive Anode of the zener diode; the maximum forward voltage drop is 0.9 V at IF = 10 mA and the junction temperature range is -55 to +125 °C.
