AZ23B5V1-HE3-18

Overview

The AZ23B5V1-HE3-18 is a dual common anode silicon planar Zener diode array manufactured by Vishay General Semiconductor - Diodes Division. It features a nominal Zener voltage of 5.1 V with a tight tolerance of ±2%. The device operates within a test current range of 2 to 5 mA and provides a maximum reverse leakage current of 0.1 µA at a reverse voltage of 4.85 V. Packaged in a compact SOT-23 surface-mount format, it supports a power dissipation of up to 500 mW on FR-4 boards and withstands junction temperatures up to 150 °C.

Feature Summary

• Dual common anode configuration for space-efficient circuit designs
• High ESD protection capability exceeding 8 kV via human body model
• Automotive-grade qualification compliant with AEC-Q101 standards

Applications

• Voltage reference circuits requiring precise dual-channel regulation
• ESD protection networks in automotive electronic modules
• Signal conditioning stages utilizing common anode topology

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package tape width and reel quantity. Ensure the component meets RoHS compliance requirements for your manufacturing process. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability before finalizing procurement orders.

Selection Notes

Select this component when a dual Zener array with a 5.1 V nominal voltage and ±2% tolerance is required. The SOT-23 package is suitable for high-density surface mount applications. Confirm that the operating temperature range of -55 °C to +150 °C aligns with the environmental conditions of the target system design.

Part Context

This device belongs to the AZ23 series of small signal Zener diodes from Vishay Semiconductors. The series offers a wide range of Zener voltages from 2.2 V to 75 V in both single and dual configurations. The HE3 suffix indicates AEC-Q101 qualification, distinguishing it from commercial grade variants while maintaining lead-free construction.

Replacement Considerations

Direct substitutes include other AZ23B5V1 variants with different packaging options, such as AZ23B5V1-E3-08 or AZ23B5V1-HE3_A-08. Verify pinout compatibility and electrical specifications before substituting.
