AZ23C36-HE3_A-08

Overview

The AZ23C36-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 ±5% tolerance and operates at a test current of 2 mA. The device has a maximum reverse leakage current of 50 nA and a dynamic resistance of 87 Ω. Qualified to AEC-Q101 standards, it supports a junction temperature up to 150 °C and offers ESD protection exceeding 8 kV (HBM) and 800 V (MM).

Feature Summary

• Dual common anode configuration for space-efficient circuit designs.
• Automotive-grade reliability through AEC-Q101 qualification.
• High electrostatic discharge robustness for sensitive environments.

Applications

• Voltage reference circuits requiring dual stable potentials.
• Clamping applications in automotive electronic modules.
• Protection stages for signal lines in industrial control systems.

Procurement Notes

Verify component authenticity by cross-referencing the ordering code against official Vishay documentation. Confirm that the HE3_A suffix indicates AEC-Q101 automotive qualification rather than commercial grade. Ensure packaging specifications match project requirements before finalizing acquisition.

Selection Notes

Select this part when a dual Zener solution with common anode topology is required within a compact SOT-23 footprint. Consider the specific 36 V nominal voltage and 2 mA test current conditions during circuit design. Verify thermal management capabilities align with the specified power dissipation limits under expected operating temperatures.

Part Context

This component belongs to the Vishay AZ23 series of small signal Zener diodes. The series provides various voltage options graded according to the E24 standard. The HE3_A variant specifically denotes RoHS compliance combined with automotive qualification, distinguishing it from the standard commercial E3 versions.
