Comchip · Zener Diodes · SOD-123
ABZT52C3V9-HF from Comchip, 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, marked by the cathode band on the package; for the ABZT52C3V9-HF it is the positive side in reverse breakdown, with a nominal Zener voltage of 3.9 V (3.70 V to 4.10 V) at IZT = 5 mA. |
| 2 | A | passive | Anode, the end without the cathode band; PD is 500 mW on ceramic PCB and forward voltage is 0.9 V at IF = 10 mA. |
