Voltage regulator diodes
Rev. 4 — 1 January 2023
Product data sheet
1. General description
Low-power voltage regulator diodes in a small SOD323 (SC-76) Surface-Mounted Device (SMD) plastic package.
The diodes are available in the normalized E24 ±1 % (BZX384-A), ±2 % (BZX384-B) and approximately ±5 % (BZX384-C) tolerance range. The series includes 37 breakdown voltages with nominal working voltages from 2.4 V to 75 V.
2. Features and benefits
• Total power dissipation: ≤300 mW • Three tolerance series: ±1 %, ±2 % and approximately ±5 % • Working voltage range: nominal 2.4 V to 75 V (E24 range) • Non-repetitive peak reverse power dissipation: ≤ 40 W
3. Applications
• General regulation functions
