AZ23C3V0-HE3_A-08

Overview

The AZ23C3V0-HE3_A-08 is a dual common anode silicon planar Zener diode array from the Vishay AZ23 series. It features a nominal Zener voltage of 3.0 V with a ±5% tolerance, tested at a current of 5 mA. The device operates within a temperature range of -55 °C to +150 °C and dissipates up to 300 mW on an FR-4 board. Packaged in a SOT-23 (TO-236AB) housing, it is AEC-Q101 qualified for automotive applications and complies with RoHS standards.

Feature Summary

• Dual common anode configuration integrating two Zener elements in a single compact package
• AEC-Q101 qualification ensuring suitability for demanding automotive electronic environments
• High electrostatic discharge protection capability exceeding 8 kV via human body model

Applications

• Automotive circuit voltage regulation and reference generation
• Protection against transient overvoltage events in sensitive electronics
• Clamping circuits requiring dual independent voltage references

Procurement Notes

Verify component authenticity by cross-referencing the ordering code with official Vishay documentation. Confirm that the HE3_A suffix indicates AEC-Q101 automotive qualification and RoHS compliance. Ensure the specific tape and reel packaging matches the required quantity specifications for production integration.

Selection Notes

Select this variant when a dual common anode topology is required for space-constrained designs. The HE3_A suffix specifically denotes automotive-grade reliability compared to commercial versions. Verify that the 3.0 V nominal voltage aligns with the target circuit requirements before finalizing the design.
