AZ23B6V8-HE3_A-08

Overview

The AZ23B6V8-HE3_A-08 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 6.8 V with a tight tolerance of ±2%. 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 offers high ESD protection exceeding 8 kV (HBM) and 800 V (MM).

Feature Summary

• Dual common anode configuration integrating two Zener elements in a single compact surface-mount package.
• AEC-Q101 qualification ensuring reliability and compliance with automotive electronic component standards.
• High electrostatic discharge robustness providing superior circuit protection against transient events.

Applications

• Automotive electronics requiring AEC-Q101 compliant voltage regulation components.
• Precision voltage reference circuits utilizing the ±2% tolerance specification.
• ESD protection networks for sensitive signal lines in consumer and industrial equipment.

Procurement Notes

Verify the specific ordering code suffix to confirm the required tolerance level and tape-and-reel packaging quantity. Ensure that the procurement specifications explicitly require AEC-Q101 qualification to match the HE3_A designation. Cross-reference the manufacturer's latest documentation to confirm current production status and availability before finalizing supply agreements.

Selection Notes

Select this component when a dual Zener array with a common anode topology is required for space-constrained designs. The ±2% tolerance makes it suitable for precision applications where standard ±5% devices are insufficient. Verify that the operating environment falls within the specified -55 °C to +150 °C temperature range and that the power dissipation requirements do not exceed the thermal limits defined for the SOT-23 footprint.

Part Context

This part belongs to the Vishay AZ23 series of small signal Zener diodes. The series provides a wide range of standardized voltages based on the E24 series. The 'B' designation indicates the tighter ±2% voltage tolerance, while the 'HE3_A' suffix denotes RoHS compliance combined with AEC-Q101 automotive qualification.

Replacement Considerations

Direct replacements must maintain the SOT-23-3 package, 6.8 V nominal voltage, and ±2% tolerance. Verify that any substitute component also holds AEC-Q101 qualification if used in automotive contexts. Check dynamic resistance and leakage current specifications to ensure equivalent performance in the target circuit design.
