Overview
The AZ23C39-HE3_A-18 is a dual common anode silicon planar Zener diode array from the Vishay AZ23 series. It features a nominal Zener voltage of 39 V with a ±5% tolerance, tested at a current of 2 mA. The device provides a maximum dynamic resistance of 87 Ω and a reverse leakage current of 50 nA at 29 V. Rated for AEC-Q101 automotive qualification, it operates within a temperature range of -55 °C to +150 °C. Packaged in a SOT-23 surface-mount housing, it dissipates up to 300 mW on an FR-4 board.
Feature Summary
- Dual common anode configuration integrating two Zener elements into a single compact package
- Automotive-grade reliability certified under the AEC-Q101 standard
- Robust electrostatic discharge protection exceeding 8 kV via human body model testing
Applications
- Voltage reference circuits requiring dual independent regulation channels
- Overvoltage protection stages in automotive electronic control units
