Overview
The AZ23B7V5-HE3-08 is a dual common anode silicon planar Zener diode array from Vishay Semiconductors, housed in an SOT-23 package. It features a nominal Zener voltage of 7.5 V with a tight tolerance of ±2%. The device operates within a temperature range of -55 °C to +150 °C and is qualified under AEC-Q101 standards for automotive applications. Electrical characteristics include a maximum reverse leakage current of 0.1 μA at 5 V and a dynamic resistance of 7 Ω at a test current of 5 mA.
Feature Summary
- Dual common anode configuration for space-efficient circuit designs
- AEC-Q101 qualification ensuring reliability in automotive environments
- High ESD protection capability exceeding 8 kV via human body model
Applications
- Automotive electronic systems requiring robust voltage regulation
- Precision reference voltage generation in compact surface-mount layouts

Procurement Notes
Verify component authenticity by cross-referencing the ordering code against official Vishay documentation. Confirm that the HE3_A suffix corresponds to the required AEC-Q101 qualification status. Ensure the specific tape and reel packaging matches the manufacturing revision indicated in the datasheet before finalizing procurement orders.
Selection Notes
Select this variant when a precise 7.5 V reference with ±2% tolerance is required in a dual-diode arrangement. The common anode structure allows independent control of two Zener paths sharing a single ground connection. Verify that the thermal dissipation limits on FR-4 boards align with the expected operating conditions of the target application.
Part Context
This component belongs to the AZ23 series of small signal Zener diodes manufactured by Vishay General Semiconductor - Diodes Division. The series offers various voltage grades and tolerance options, with the 'B' designation indicating the tighter ±2% specification compared to the standard ±5% grade.
