Voltage regulator diodes

Low-power voltage regulator diodes in a small SOT23 (TO-236AB) Surface-Mounted Device (SMD) plastic package.

The diodes are available in the normalized E24 ±1 % (BZX84-A), ±2 % (BZX84-B) and approximately ±5 % (BZX84-C) tolerance range. The series includes 37 breakdown voltages with nominal working voltages from 2.4Vto75 V.


  • Total power dissipation: ≤ 250 mW
  • Three tolerance series: ±1%, ±2% and approximately ±5%
  • AEC-Q101 qualified
  • Working voltage range: nominal 2.4 V to 75 V (E24 range)
  • Non-repetitive peak reverse power dissipation: ≤ 40 W

Target applications

  • General regulation functions
