AZ23B24-HE3_A-18

Overview

The AZ23B24-HE3_A-18 is a silicon planar Zener diode from the Vishay AZ23 series, housed in an SOT-23 surface-mount package. It features a nominal Zener voltage of 24 V with a tight tolerance of ±2%. The device operates at a test current of 5 mA and has a maximum reverse leakage current of 0.05 µA at 18 V. Dynamic resistance is specified at 70 Ω (at Izt1) and 220 Ω (at Izt2). It is AEC-Q101 qualified for automotive applications, supports a junction temperature up to 150 °C, and provides ESD protection exceeding 8 kV (HBM) and 800 V (MM).

Feature Summary

AEC-Q101 qualified for automotive reliability standards.
High electrostatic discharge (ESD) capability per AEC-Q101 specifications.
RoHS-compliant construction with lead-free soldering compatibility.

Applications

Automotive electronic circuit voltage regulation.
Precision reference voltage generation in compact modules.
Over-voltage protection for sensitive signal lines.

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer's part number against official Vishay documentation. Confirm that the specific ordering suffix matches the required tape-and-reel quantity and packaging format. Ensure compliance with RoHS directives and AEC-Q101 qualification requirements before finalizing procurement orders.

Selection Notes

Select this variant when a precise 24 V reference with ±2% tolerance is required. The HE3_A suffix indicates AEC-Q101 qualification, making it suitable for automotive environments. Verify that the 5 mA test current aligns with the target circuit's power consumption constraints and thermal dissipation capabilities within the SOT-23 footprint.

Part Context

This component belongs to the AZ23 series of small-signal Zener diodes manufactured by Vishay General Semiconductor - Diodes Division. The series utilizes silicon planar technology and offers a wide range of standardized Zener voltages. The AZ23B24-HE3_A-18 specifically denotes the 24 V version with high precision and automotive-grade qualification.
