AZ23B33-HE3_A-08

Overview

The AZ23B33-HE3_A-08 is a dual common anode silicon planar Zener diode array from the Vishay AZ23 series, housed in a SOT-23 package. It features a nominal Zener voltage of 33 V with a tight tolerance of ±2%. The device is AEC-Q101 qualified for automotive applications and RoHS compliant. Electrical characteristics include a maximum reverse leakage current of 50 µA at 29 V and a dynamic resistance of 80 Ω at a test current of 2 mA. It operates within a temperature range of -55 °C to +150 °C.

Feature Summary

Dual common anode configuration providing two independent Zener references in a single compact surface-mount package.
Automotive-grade qualification ensuring reliability under strict environmental and operational standards.
Tight voltage tolerance grading allows for precise reference applications without requiring external trimming.

Applications

Voltage reference circuits in automotive electronic control units (ECUs).
Over-voltage protection stages in vehicle infotainment systems.
Signal conditioning and clamping in automotive sensor interfaces.

Procurement Notes

Verify that the ordering suffix matches the required tape-and-reel packaging format. Confirm the specific AEC-Q101 qualification status if the application demands formal automotive compliance documentation. Ensure the component version aligns with the latest datasheet revision to avoid discrepancies in electrical parameters or marking codes during production integration.

Selection Notes

Select this part when a dual Zener solution is required in a minimal footprint. The ±2% tolerance variant is suitable for precision analog circuits where standard commercial grades are insufficient. Consider the thermal resistance limits and power derating curves when designing for high ambient temperatures or continuous operation near the maximum junction temperature rating.

Part Context

This component belongs to the AZ23 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series offers a wide range of standardized voltage values graded according to the E24 standard. The HE3_A suffix specifically denotes the AEC-Q101 qualified, lead-free variant designed for robust automotive environments.
