AZ23C2V7-HE3_A-18

Overview

The AZ23C2V7-HE3_A-18 is a dual common anode silicon planar Zener diode array from the Vishay AZ23 series, housed in a SOT-23 surface-mount package. It features a nominal Zener voltage of 2.7 V with a ±5% tolerance and a maximum power dissipation of 300 mW on an FR-4 board. The device operates within a temperature range of -55 °C to +150 °C and carries AEC-Q101 qualification for automotive applications.

Feature Summary

• Dual common anode configuration providing two independent Zener elements in a single compact package
• AEC-Q101 qualified for enhanced reliability in automotive environments
• High electrostatic discharge (ESD) protection capability exceeding 8 kV via human body model

Applications

• Automotive electronic circuits requiring robust voltage regulation
• Protection against transient voltage spikes in sensitive signal lines
• Reference voltage generation in low-voltage analog systems

Procurement Notes

Verify that the ordering suffix HE3_A confirms AEC-Q101 automotive qualification and RoHS compliance. Confirm the -18 suffix indicates a 10,000-unit reel packaging format. Ensure the specific part number matches the required 2.7 V nominal voltage and ±5% tolerance specifications before finalizing procurement orders.

Selection Notes

Select this component when a dual Zener array with common anode topology is required for space-constrained designs. The 2.7 V nominal voltage suits low-voltage reference applications. Verify that the 300 mW power dissipation rating meets the thermal requirements of the target operating environment.
