Overview
The AZ23B6V2-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 6.2 V with a tight tolerance of ±2%. The device is AEC-Q101 qualified for automotive applications and housed in a compact SOT-23 package. Key electrical parameters include a maximum reverse leakage current of 0.1 µA at 5 V and a dynamic resistance of 10 Ω at a test current of 5 mA. It operates within a temperature range of -55 °C to +150 °C.
Feature Summary
- Dual common anode configuration providing two independent Zener references in a single package
- AEC-Q101 qualification ensuring reliability for demanding automotive environments
- High ESD protection capability exceeding 8 kV via human body model standards
- Tight voltage tolerance of ±2% for precise reference applications
Applications
- Automotive circuit voltage regulation and clamping
- Precision voltage reference generation in dual-channel designs
- ESD protection for sensitive signal lines
- Over-voltage protection in automotive control modules
Procurement Notes
Verify that the ordering suffix matches the required tape and reel specifications. Confirm the presence of the HE3_A designation to ensure AEC-Q101 automotive qualification is included. Check RoHS compliance status against specific project requirements before finalizing procurement orders.
Selection Notes
Select this component when a dual Zener array with high precision is required. The ±2% tolerance makes it suitable for applications needing tighter voltage accuracy than standard commercial grades. Ensure the common anode topology aligns with the circuit design requirements for the specific application.
Part Context
This part belongs to the AZ23 series of small signal Zener diodes. The series offers a wide range of Zener voltages from 2.2 V to 75 V. The AZ23B variant specifically denotes the 2% tolerance grade, while the HE3_A suffix indicates AEC-Q101 qualification and RoHS compliance.
Replacement Considerations
AZ23B6V2-E3-18: Commercial grade version without AEC-Q101 qualification.
