BZT52HC3V3WF-7
Diodes Incorporated · Zener Diodes · SOD-123F
BZT52HC3V3WF-7 from Diodes Incorporated, in a SOD-123F. 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 (BZT52HC3V3WF, VZ 3.1-3.5V at IZT 5mA) is reverse-biased with the cathode positive, and the datasheet gives a 1cm2 cathode mounting pad for the 830mW rating. |
| 2 | A | passive | Anode, the terminal opposite the cathode band; the datasheet states forward voltage of 0.9V at IF = 10mA and maximum forward current of 250mA. |
