Nexperia · Zener Diodes · SOD-523(SC-79)
BZX585-B36 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 of the Zener diode, identified by the marking bar; operates as the reverse-biased regulation terminal (VZ nominal 36 V for the B36, ±2 % tolerance). |
| 2 | A | passive | Anode of the Zener diode; connects to the lower-potential side in normal reverse-regulation use. |
