AZ23B16-HE3_A-08

Overview

The AZ23B16-HE3_A-08 is a dual common anode silicon planar Zener diode array from the Vishay AZ23 series. It provides a nominal Zener voltage of 16 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 300 mW on an FR-4 board. It features high ESD protection exceeding 8 kV (HBM) and 800 V (MM). The component is AEC-Q101 qualified, RoHS compliant, and supplied in tape and reel packaging.

Feature Summary

• Dual common anode configuration for space-efficient circuit design
• AEC-Q101 automotive qualification ensuring reliability under harsh conditions
• High electrostatic discharge robustness exceeding standard thresholds
• Tight voltage tolerance of ±2% for precise regulation applications

Applications

• Automotive electronic systems requiring AEC-Q101 compliance
• Voltage reference circuits demanding stable low-tolerance outputs
• ESD protection stages in sensitive signal lines
• Power supply overvoltage clamping and regulation

Procurement Notes

Verify that the ordering code matches the specific suffix requirements for automotive grade and tape quantity. Confirm RoHS3 compliance status during final procurement checks. Ensure the supplier provides traceability documentation consistent with AEC-Q101 standards. Validate package orientation markings against schematic footprints before assembly.

Selection Notes

Select this variant when a 16 V reference requires tighter than standard tolerance. The HE3_A suffix indicates automotive qualification and RoHS compliance. Verify thermal management capabilities if operating near maximum power dissipation limits. Consider the common anode topology for shared ground or reference connections in dual-channel designs.

Part Context

This component belongs to the Vishay AZ23 series of small signal Zener diodes. The series offers a wide range of voltages from 2.2 V to 75 V. Variants are available with different tolerances and packaging options. The AZ23B16 specifically denotes the 16 V nominal voltage with 2% tolerance.

Replacement Considerations

AZ23B16-E3-08: Commercial grade equivalent without automotive qualification. AZ23B16-G3-08: Alternative RoHS-compliant commercial version. AZ23B16-HE3-08: Previous generation automotive variant.
