AZ23C10-HE3-18

Overview

The AZ23C10-HE3-18 is a dual common anode silicon planar Zener diode array manufactured by Vishay General Semiconductor - Diodes Division. It features a nominal Zener voltage of 10 V with a ±5% tolerance, tested at a current of 5 mA. The device has a maximum reverse leakage current of 0.1 µA and a dynamic resistance of 15 Ω. Rated for a power dissipation of 300 mW on an FR-4 board, it operates within a temperature range of -55 °C to +150 °C. Packaged in a SOT-23-3 surface-mount case, this component is AEC-Q101 qualified and RoHS compliant.

Feature Summary

• Dual common anode configuration providing two independent Zener elements in a single package
• AEC-Q101 automotive qualification ensuring reliability under specified stress conditions
• ESD protection capability exceeding 8 kV via human body model and 800 V via machine model
• RoHS compliance utilizing lead-free soldering materials

Applications

• Voltage reference circuits requiring dual polarity or split-rail supplies
• Overvoltage protection stages in automotive electronic control units
• Clamping applications for transient voltage suppression in signal lines

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation before procurement. Confirm that the HE3_A variant designation aligns with the required AEC-Q101 qualification status. Ensure the tape and reel packaging matches the intended automated assembly equipment specifications. Cross-reference the exact part number to confirm availability and manufacturing status.

Selection Notes

Select this component when a dual Zener array with a 10 V nominal breakdown is required in a compact SOT-23 footprint. Consider the 300 mW thermal rating on standard PCBs for power dissipation limits. Verify that the ±5% voltage tolerance meets the circuit requirements. Ensure the operating temperature range covers the expected environmental extremes of the application.

Part Context

This device belongs to the AZ23 series of small signal Zener diodes from Vishay. The series offers a wide range of standardized voltages from 2.2 V to 75 V. Variants are available with different tolerances and packaging options to suit commercial and automotive design needs.

Replacement Considerations

Publicly confirmed substitute part numbers include AZ23C10-HE3_A-08 and AZ23C10-E3-18. These alternatives share the same electrical characteristics and package type but may differ in reel quantity or specific qualification markings.
