# BZX585-C47

**Nexperia** · Zener Diodes · SOD-523(SC-79)

BZX585-C47 from Nexperia, in a SOD-523(SC-79). 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; the marking bar on the package indicates the cathode, and the cathode tab is the reference for the stated thermal resistance and the 35 mm² Cu area mounting condition. |
| 2 | A | passive | Anode of the Zener diode; the datasheet gives no separate electrical limit for this pin beyond the device ratings (IF max 200 mA, Ptot max 300 mW). |
