# CZRF52C5V6-HF

**Comchip** · Zener Diodes · SOD-323F

CZRF52C5V6-HF 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, marked by the cathode band; the Zener (5.1-5.88 V range for the 5V6 part, 5.32 V min to 5.88 V max at IZ=5 mA) voltage is positive on this terminal in reverse breakdown. |
| 2 | A | passive | Anode terminal of the Zener diode; maximum forward voltage drop is 0.9 V at IF = 10 mA. |
