AZ23C5V1-HE3-18

Overview

The AZ23C5V1-HE3-18 is a silicon planar Zener diode array from Vishay, configured as one pair with a common anode. It features a nominal Zener voltage of 5.1 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 is AEC-Q101 qualified for automotive applications. Packaged in an SOT-23 case, it delivers high ESD protection exceeding 8 kV (HBM) and 800 V (MM).

Feature Summary

AEC-Q101 qualified for automotive reliability standards.
High electrostatic discharge capability exceeding 8 kV human body model.
RoHS-compliant construction utilizing advanced planar technology.

Applications

Automotive electronic circuit protection.
Voltage reference stabilization in dual-channel systems.
Transient voltage suppression in surface-mount assemblies.

Procurement Notes

Verify the specific HE3_A suffix indicates AEC-Q101 qualification status. Confirm the -18 suffix corresponds to the 10,000-unit reel packaging format. Ensure compliance with RoHS3 directives before finalizing component selection.

Selection Notes

Select this variant when dual-channel voltage regulation is required in a compact footprint. The common anode configuration simplifies circuit layout compared to separate discrete components. Verify thermal constraints against the 300 mW dissipation limit on standard PCBs.

Part Context

This component belongs to the AZ23 series of small signal Zener diodes manufactured by Vishay General Semiconductor. The series offers various voltage grades according to the E24 standard. The HE3 designation identifies the specific lead-free and AEC-Q101 qualified product line within the broader family.
