AZ23C2V7-HE3_A-08

Overview

The AZ23C2V7-HE3_A-08 is a silicon planar Zener diode array from the Vishay AZ23 series, housed in an SOT-23 package. It features a dual common anode configuration with two independent elements. The nominal Zener voltage is 2.7 V with a tolerance of ±5 %. Electrical characteristics are defined at a test current of 5 mA, yielding a maximum reverse leakage current of 1 μA and a dynamic resistance of 83 Ω. The device supports a power dissipation of up to 500 mW and operates within a junction temperature range of -55 °C to +150 °C.

Feature Summary

• Dual common anode configuration for space-efficient circuit designs
• AEC-Q101 qualified for automotive reliability standards
• High electrostatic discharge protection capability exceeding 8 kV via human body model

Applications

• Automotive electronic circuits requiring AEC-Q101 compliance
• Voltage reference applications utilizing low-voltage regulation
• ESD protection stages in signal conditioning paths

Procurement Notes

Verify the specific ordering suffix against the manufacturer's documentation to confirm the tape and reel packaging format. Ensure that the HE3_A designation aligns with the required automotive qualification level for the target application environment. Cross-reference the component marking code D41 during incoming inspection to validate authenticity.

Selection Notes

Select this component when a dual Zener array with a 2.7 V nominal rating is required in a compact surface-mount footprint. The HE3_A suffix indicates AEC-Q101 qualification, making it suitable for automotive environments where standard commercial grade parts may not suffice. Consider the 83 Ω dynamic resistance for precision requirements.

Part Context

This part belongs to the AZ23 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series offers a wide range of Zener voltages from 2.2 V to 75 V in the SOT-23 package. The HE3_A variant specifically denotes RoHS compliance combined with automotive qualification, distinguishing it from the standard E3 commercial grade versions.

Replacement Considerations

Direct substitutes include other AZ23C2V7 variants such as AZ23C2V7-E3-08 for non-automotive use or AZ23B2V7-HE3_A-08 for tighter ±2 % tolerance requirements. Verify pinout compatibility and thermal resistance parameters before substitution.
