AZ23B3V3-HE3_A-18

Overview

The AZ23B3V3-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 two independent Zener diodes sharing a single anode terminal. The nominal Zener voltage is 3.3 V with a tight tolerance of ±2%. Electrical characteristics include a maximum reverse leakage current of 5 µA at 1 V and a dynamic resistance of 95 Ω at a test current of 5 mA. The device is AEC-Q101 qualified for automotive applications and operates within a junction temperature range of -55 °C to +150 °C.

Feature Summary

Dual common-anode Zener diode array providing two independent voltage references in a compact SOT-23 footprint.
AEC-Q101 qualified for automotive-grade reliability and high ESD protection capability exceeding 8 kV (HBM).
Tight voltage tolerance of ±2% ensures precise regulation for sensitive circuitry.
RoHS-compliant construction utilizing advanced HE3 technology.

Applications

Automotive electronic systems requiring robust voltage reference components.
ESD protection circuits for data lines and signal interfaces.
Precision voltage regulation in portable consumer electronics.

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number against official Vishay documentation. Confirm that the specific ordering suffix matches the required tape-and-reel packaging format and AEC-Q101 qualification status before finalizing procurement orders.

Selection Notes

Select this variant when a dual-diode configuration with a common anode is required. The 'B' designation indicates a strict ±2% voltage tolerance, while the 'HE3_A' suffix confirms AEC-Q101 automotive qualification. Ensure the 3.3 V nominal voltage aligns with the target circuit's reference requirements.

Part Context

This component belongs to the Vishay AZ23 series of small-signal Zener diodes. The series offers a wide range of standard Zener voltages from 2.2 V to 75 V across various tolerance grades and packaging options, designed for general-purpose voltage regulation and protection tasks.
