AZ23B36-HE3_A-08

Overview

The AZ23B36-HE3_A-08 is a dual common anode silicon planar Zener diode array from the Vishay AZ23 series, housed in an SOT-23 package. It features a nominal Zener voltage of 36 V with a tight tolerance of ±2%. The device is AEC-Q101 qualified for automotive reliability and RoHS compliant. Electrical characteristics include a maximum reverse leakage current of 50 µA at 27 V and a dynamic resistance of 87 Ω at a test current of 2 mA. It operates within a temperature range of -55 °C to +150 °C and dissipates up to 300 mW on a standard FR-4 board.

Feature Summary

• Dual common anode configuration integrating two Zener diodes in a single compact surface-mount package.
• Automotive-grade qualification ensuring high reliability and robustness under stringent environmental conditions.
• High electrostatic discharge (ESD) protection capability exceeding 8 kV via human body model standards.

Applications

• Voltage reference circuits requiring precise dual-channel regulation.
• Clamping and protection stages in automotive electronic control units.
• Over-voltage suppression networks in industrial sensor interfaces.

Procurement Notes

Verify that the ordering suffix matches the required tape-and-reel quantity and packaging format. Confirm the specific AEC-Q101 qualification status and RoHS compliance documentation aligns with project requirements. Ensure the component is sourced from authorized distributors to guarantee authenticity and traceability throughout the supply chain.

Selection Notes

Select this variant when a ±2% voltage tolerance is mandatory for circuit precision. Choose the HE3_A suffix specifically for applications demanding automotive-grade reliability and ESD robustness. Verify that the 300 mW power dissipation rating on FR-4 meets the thermal design constraints of the target application environment.

Part Context

This component belongs to the Vishay AZ23 series of small signal Zener diodes. The series offers a wide range of standardized voltages from 2.2 V to 75 V. The 'B' designation indicates the tighter ±2% tolerance grade, while the 'HE3_A' suffix denotes the automotive-qualified, lead-free variant packaged in standard reels for automated assembly processes.
