Voltage regulator diodes

Low-power voltage regulator diodes encapsulated in an ultra small SOD523 plastic SMD package.

The diodes are available in the normalized E24 +- 2 pct (BZX585-B) and +- 5 pct (BZX585-C) tolerance range.

The series consists of 37 types with nominal working voltages from 2.4 V to 75 V.


  • Total power dissipation: max. 300 mW
  • Two tolerance series: +- 2 pct and +- 5 pct
  • Working voltage range: nominal 2.4 V to 75 V (E24 range)
  • Non-repetitive peak reverse power dissipation: max. 40 W.
  • AEC-Q101 qualified

Target applications

  • General regulation functions.
