BZV85-C24 from Nexperia, in a DO-41. 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, identified by the marking band on the package; the regulator is operated with this pin positive relative to the anode in reverse breakdown (VZ for BZV85-C24 is 22.8 V to 25.6 V at Itest = 10 mA). |
| 2 | A | passive | Anode; forward current is limited to 500 mA max and forward voltage is max 1 V at IF = 50 mA. |
