AZ23B2V7-HE3_A-18

Overview

The AZ23B2V7-HE3_A-18 is a silicon planar Zener diode array from the Vishay AZ23 series, housed in an SOT-23 surface-mount package. It features a dual common-anode configuration with a nominal Zener voltage of 2.7 V and 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 reliability and complies with RoHS standards.

Feature Summary

• AEC-Q101 qualified for automotive applications
• Dual common-anode Zener diode array
• Tight ±2% Zener voltage tolerance
• High ESD protection capability

Applications

• Automotive voltage regulation circuits
• Precision reference voltage generation
• ESD protection networks

Procurement Notes

Verify the specific ordering code suffix against current manufacturer documentation to confirm tape-and-reel quantities and packaging specifications. Ensure that the component's AEC-Q101 qualification aligns with target automotive reliability requirements before finalizing procurement orders.

Selection Notes

Select this part when a precise 2.7 V reference with ±2% tolerance is required in a compact SOT-23 footprint. The HE3_A suffix indicates AEC-Q101 qualification, making it suitable for automotive environments where standard commercial grade devices may not meet durability standards.

Part Context

This component belongs to the Vishay AZ23 series of small signal Zener diodes. The series offers a wide range of voltages from 2.2 V to 75 V in both ±5% (C) and ±2% (B) tolerances. The AZ23B2V7 variant specifically targets applications requiring tighter voltage accuracy than the standard commercial grade.
