Overview
The AZ23C2V7-HE3-08 is a dual common anode silicon planar Zener diode array from the Vishay AZ23 series, housed in a SOT-23 surface-mount package. It provides a nominal Zener voltage of 2.7 V with a ±5% tolerance and a maximum dynamic resistance of 83 Ω at a test current of 5 mA. The device supports a maximum power dissipation of 300 mW on an FR-4 board and operates within a temperature range of -55 °C to +150 °C. It carries AEC-Q101 qualification for automotive reliability.
Feature Summary
- Dual common anode configuration for space-efficient circuit design
- AEC-Q101 qualified for automotive-grade reliability
- ESD protection exceeding 8 kV (HBM) and 800 V (MM)
- RoHS-compliant construction
Applications
- Automotive electronic circuits requiring robust ESD protection
