AZ23B16-HE3-18

Overview

The AZ23B16-HE3-18 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 16 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 500 mW on a lead or 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

• AEC-Q101 qualified for automotive reliability requirements.
• High electrostatic discharge (ESD) capability exceeding 8 kV human body model.
• Dual common-anode configuration for compact circuit design.
• Tight Zener voltage tolerance of ±2% for precision regulation.

Applications

• Automotive electronic circuits requiring robust voltage reference.
• Precision voltage clamping and protection stages.
• Compact power supply regulation modules.

Procurement Notes

Verify the specific ordering code suffix against the manufacturer's current documentation to confirm tape-and-reel quantities and RoHS compliance status. Ensure that the AEC-Q101 qualification aligns with target automotive application standards before finalizing procurement orders.

Selection Notes

Select this component when a precise 16 V reference with ±2% tolerance is required in a small SOT-23 footprint. The HE3_A suffix indicates AEC-Q101 qualification, making it suitable for automotive environments where standard commercial grade devices may not suffice.

Part Context

This part belongs to the AZ23 series of small signal Zener diodes manufactured by Vishay General Semiconductor - Diodes Division. The series provides a wide range of Zener voltages from 2.2 V to 75 V in a standardized SOT-23 package, offering options for both commercial and automotive grades.
