AZ23B39-HE3_A-18

Overview

The AZ23B39-HE3_A-18 is a dual common anode silicon planar Zener diode array from the Vishay AZ23 series, housed in a SOT-23 surface-mount package. It features a nominal Zener voltage of 39 V with a tight tolerance of ±2%. The device is AEC-Q101 qualified for automotive applications and operates within a temperature range of -55 °C to +150 °C. Electrical characteristics include a maximum reverse leakage current of 50 µA at 29 V and a dynamic resistance of 87 Ω at a test current of 2 mA.

Feature Summary

Dual common anode configuration providing two independent Zener channels in a single compact package
AEC-Q101 qualification ensuring reliability for demanding automotive electronic environments
High ESD protection capability exceeding 8 kV via human body model standards
Tight voltage tolerance of ±2% for precise reference and regulation applications

Applications

Automotive circuit voltage clamping and protection
Precision voltage reference generation
Transient voltage suppression in sensitive electronics

Procurement Notes

Verify component authenticity by cross-referencing the ordering code against official Vishay documentation. Confirm that the HE3_A suffix indicates AEC-Q101 qualification and RoHS compliance. Ensure the -18 suffix matches the required 10,000-unit reel packaging format for your assembly process.

Selection Notes

Select this variant when a ±2% voltage tolerance is required instead of the standard ±5% available in the 'C' series. Verify that the 39 V breakdown voltage aligns with the specific circuit requirements. Consider the SOT-23 footprint constraints and the thermal dissipation limits on the FR-4 board during design integration.

Part Context

This part belongs to the AZ23 series of small signal Zener diodes manufactured by Vishay General Semiconductor - Diodes Division. The series offers a wide range of Zener voltages from 2.2 V to 75 V in a standardized SOT-23 package, allowing for consistent design practices across various voltage levels.
