AZ23C5V6-HE3-18

Overview

The AZ23C5V6-HE3-18 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 5.6 V with a ±5% tolerance and a test current of 5 mA. The device has a maximum reverse leakage current of 1 µA at 1 V and a dynamic resistance of 40 Ω at 1 kHz. It is AEC-Q101 qualified for automotive applications, operates within a temperature range of -55 °C to +150 °C, and dissipates up to 300 mW on an FR-4 board.

Feature Summary

• Dual common anode configuration for space-efficient circuit designs
• AEC-Q101 qualified for automotive reliability standards
• ESD protection exceeding 8 kV (HBM) and 800 V (MM)
• RoHS-compliant construction

Applications

• Automotive voltage regulation circuits
• Signal clamping and protection stages
• Reference voltage generation in low-power systems

Procurement Notes

Verify the specific ordering code suffix against the manufacturer's official documentation to confirm tape-and-reel specifications and minimum order quantities. Ensure that the component selection aligns with the required AEC-Q101 qualification status and RoHS compliance mandates for the intended production environment.

Selection Notes

Select this variant when a dual common anode topology is required alongside strict automotive qualification standards. The 5.6 V nominal voltage and ±5% tolerance suit general-purpose regulation tasks. Verify thermal management requirements, as power dissipation drops significantly above ambient temperatures exceeding 75 °C.

Part Context

This part belongs to the AZ23 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series offers various voltage grades based on the E24 standard and includes options for different tolerances and packaging formats. The HE3 suffix denotes AEC-Q101 qualification, distinguishing it from commercial grade variants.

Replacement Considerations

Direct replacements include other AZ23 series parts with identical electrical characteristics but different voltages or tolerances, such as AZ23B5V6-HE3-18 for tighter tolerance. Cross-series alternatives like BZX384C5V6-HE3-18 offer single-diode configurations in similar packages but require verification of pinout compatibility.
