AZ23C11-HE3_A-08

Overview

The AZ23C11-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 provides two independent Zener channels with a nominal voltage of 11 V and a tolerance of ±5%. The device operates within a junction temperature range of -55 °C to +150 °C and dissipates up to 300 mW on an FR-4 board. It is AEC-Q101 qualified for automotive applications and features ESD protection exceeding 8 kV (HBM) and 800 V (MM).

Feature Summary

• Dual common-anode configuration providing two independent Zener channels in a single compact surface-mount package.
• AEC-Q101 qualification ensuring compliance with automotive electronic component standards.
• Integrated electrostatic discharge (ESD) protection rated above 8 kV via human body model and 800 V via machine model.

Applications

• Automotive circuit voltage regulation and reference generation.
• Protection of sensitive input lines against overvoltage transients.
• Clamping circuits in consumer electronics requiring robust ESD immunity.

Procurement Notes

Verify the specific ordering suffix '-HE3_A-08' to confirm AEC-Q101 automotive qualification and tape-and-reel packaging format. Cross-reference the manufacturer's latest datasheet revision to ensure alignment with current RoHS compliance and material categorization requirements before finalizing procurement specifications.

Selection Notes

Select this component when a dual-channel Zener array with a nominal 11 V breakdown is required in an SOT-23 footprint. Ensure the application supports the specified ±5% voltage tolerance and that the thermal design accommodates the 300 mW power dissipation limit on standard FR-4 substrates.

Part Context

This part belongs to the Vishay AZ23 series of small signal Zener diodes. The 'C' designation indicates a standard ±5% voltage tolerance, while the 'HE3_A' suffix denotes AEC-Q101 qualification and lead-free construction. The '-08' suffix specifies the standard 3000-unit reel packaging format.

Replacement Considerations

AZ23C11-E3-08: Commercial grade equivalent without automotive qualification. AZ23C11-G3-08: Green/RoHS-compliant commercial version. Verify that alternative sourcing meets the specific AEC-Q101 reliability requirements if used in automotive designs.
