# BZV85-C6V8

**Nexperia** · Zener Diodes · DO-41

BZV85-C6V8 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 | cathode | passive | Cathode of the voltage regulator diode, identified by the marking band on the package; the device is used in reverse breakdown, with working voltage VZ of 6.4 V min to 7.2 V max for the BZV85-C6V8 type (Table 8). |
| 2 | anode | passive | Anode of the voltage regulator diode, the terminal opposite the marked cathode band, used as the reference return in reverse-breakdown regulation. |
