AZ23B3V0-HE3-18

Overview

The AZ23B3V0-HE3-18 is a dual common anode silicon planar Zener diode array from the Vishay AZ23 series, housed in a SOT-23 surface-mount package. It features a nominal Zener voltage of 3.0 V with a tight ±2% tolerance and a maximum dynamic resistance of 95 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 and includes high ESD protection ratings exceeding 8 kV via the human body model.

Feature Summary

• Dual common anode configuration providing two independent Zener references in a single compact footprint
• AEC-Q101 qualified construction ensuring suitability for demanding automotive electronic environments
• High electrostatic discharge robustness exceeding 8 kV according to the human body model standard

Applications

• Automotive circuitry requiring precise low-voltage reference generation
