Overview
The AZ23B5V6-HE3_A-18 is a silicon planar Zener diode array from the Vishay AZ23 series, housed in an SOT-23 package. It features a dual common anode configuration with a nominal Zener voltage of 5.6 V and a tight tolerance of ±2%. The device operates within a temperature range of -55 °C to +150 °C and dissipates up to 300 mW on an FR-4 board. It is AEC-Q101 qualified for automotive reliability and supplied in reels of 10,000 units.
Feature Summary
- Dual common anode Zener diode array designed for compact surface-mount applications
- AEC-Q101 qualified for enhanced automotive-grade reliability and ESD protection
- Tight ±2% Zener voltage tolerance for precise reference requirements
Applications
- Automotive voltage regulation circuits
- Precision voltage reference networks
- ESD protection arrays in consumer electronics
Procurement Notes
Verify the complete ordering code matches the required specifications. Confirm that the HE3_A suffix indicates AEC-Q101 qualification and RoHS compliance. Ensure the -18 suffix corresponds to the 10,000-unit reel packaging format before finalizing procurement orders.
Selection Notes
Select this component when a dual Zener array with high precision is required. The ±2% tolerance distinguishes it from standard ±5% variants. Verify thermal management capabilities against the 300 mW dissipation limit on the target PCB footprint.
Part Context
This part belongs to the AZ23 series of small signal Zener diodes manufactured by Vishay General Semiconductor - Diodes Division. The series offers various voltage grades and tolerance options across commercial and automotive grades.
