AZ23C51-HE3_A-18

Overview

The AZ23C51-HE3_A-18 is a dual common-anode silicon planar Zener diode array from the AZ23 series, manufactured by Vishay General Semiconductor - Diodes Division. It features a nominal Zener voltage of 51 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 housed in a SOT-23 package. It holds AEC-Q101 qualification for automotive applications and complies with RoHS standards.

Feature Summary

AEC-Q101 qualified for automotive reliability requirements
Dual common-anode configuration for space-efficient circuit design
ESD protection capability exceeding 8 kV (HBM) and 800 V (MM)
RoHS compliant construction

Applications

Automotive electronic circuits requiring voltage reference or regulation
General-purpose voltage clamping and protection stages
Signal conditioning and level shifting in compact surface-mount designs

Procurement Notes

Verify that the ordering code matches AZ23C51-HE3_A-18 to ensure correct voltage, tolerance, and packaging. Confirm AEC-Q101 qualification status if automotive compliance is required. Check datasheet revision dates for updated thermal and electrical specifications before finalizing procurement.

Selection Notes

Select this component when a 51 V dual Zener array with ±5% tolerance is needed in a SOT-23 footprint. Ensure the application requires AEC-Q101 qualification and can accommodate the 300 mW power dissipation limit on standard PCBs. Verify operating temperatures remain within the specified -55 °C to +150 °C range.

Part Context

This part belongs to the AZ23 series of small signal Zener diodes offered by Vishay Semiconductors. The series provides various Zener voltages graded according to the E24 standard. The HE3_A suffix indicates AEC-Q101 qualification and RoHS compliance, while the -18 suffix denotes tape-and-reel packaging with 10,000 units per reel.
