AZ23B3V3-HE3-08

Overview

The AZ23B3V3-HE3-08 is a dual common anode silicon planar Zener diode array from Vishay, housed in a SOT-23 surface-mount package. It features a nominal Zener voltage of 3.3 V with a tight tolerance of ±2%. The device operates within a junction temperature range of -55 °C to +150 °C and dissipates up to 500 mW (300 mW on FR-4). It is AEC-Q101 qualified for automotive reliability and offers high ESD protection exceeding 8 kV via the human body model.

Feature Summary

Dual common anode configuration providing two independent Zener references in a single compact package
AEC-Q101 qualification ensuring compliance with rigorous automotive electronic component standards
High electrostatic discharge robustness exceeding 8 kV human body model limits
Tight ±2% Zener voltage tolerance for precision reference applications

Applications

Automotive circuitry requiring AEC-Q101 compliant voltage references
Precision analog signal conditioning and monitoring systems
Electrostatic discharge (ESD) protection networks

Procurement Notes

Verify that the ordering code suffix matches HE3_A-08 to confirm AEC-Q101 automotive qualification. Standard commercial versions use different suffixes. Confirm RoHS compliance status and ensure the supplier provides traceability documentation required for automotive supply chains.

Selection Notes

Select this part when a dual Zener array with strict ±2% tolerance is required. Ensure the operating current aligns with the specified test current of 5 mA. Verify thermal management capabilities if ambient temperatures approach the maximum rated junction limit.

Part Context

This component belongs to the AZ23 series of small signal Zener diodes. The 'B' designation indicates the tighter ±2% voltage tolerance compared to the standard ±5% 'C' grade. The HE3_A suffix specifically denotes the AEC-Q101 qualified automotive variant packaged in reels.
