AZ23C3V6-HE3-08

Overview

The AZ23C3V6-HE3-08 is a dual common anode silicon planar Zener diode array from the AZ23 series, manufactured by Vishay Semiconductors. It features a nominal Zener voltage of 3.6 V with a ±5% tolerance and operates at a test current of 5 mA. The device is housed in a SOT-23 package and supports a maximum power dissipation of 300 mW on an FR-4 board. It is AEC-Q101 qualified for automotive applications and offers ESD protection exceeding 8 kV (HBM) and 800 V (MM).

Feature Summary

• Dual common anode configuration within a compact SOT-23 package.
• AEC-Q101 qualification for automotive reliability standards.
• High electrostatic discharge capability per AEC-Q101 specifications.
• RoHS-compliant construction utilizing lead-free soldering materials.

Applications

• Automotive circuit voltage regulation and reference generation.
• Protection against electrostatic discharge in sensitive electronics.
• Clamping circuits requiring dual voltage references.

Procurement Notes

Verify that the ordering code includes the HE3 suffix to confirm AEC-Q101 automotive qualification. Ensure the tape and reel packaging matches the required quantity of 3000 units per 7-inch reel. Confirm RoHS compliance status through official manufacturer documentation before finalizing procurement orders.

Selection Notes

Select this component when a dual common anode Zener array is required for space-constrained designs. Verify that the 3.6 V nominal voltage aligns with the specific circuit requirements. Consider the 300 mW power dissipation limit on standard FR-4 boards during thermal design analysis.

Part Context

This part belongs to the AZ23 series of small signal Zener diodes. The series provides various voltage options graded according to the international E24 standard. Other variants include different voltage ratings and tolerance codes such as B for ±2%. The HE3 suffix specifically denotes automotive-grade qualification compared to the commercial grade E3 suffix.

Replacement Considerations

AZ23C3V6-E3-08: Commercial grade equivalent without AEC-Q101 qualification.

FAQ

What is the difference between the AZ23C3V6-HE3-08 and AZ23C3V6-E3-08?

The HE3 suffix indicates AEC-Q101 qualification for automotive applications, while the E3 suffix denotes commercial grade. Both share identical electrical characteristics but differ in manufacturing qualification standards.

How does the dual common anode configuration function?

The device contains two independent Zener diodes sharing a single common anode terminal. This allows for separate voltage regulation or clamping functions using only three connection pins.
