Overview
The AZ23B3V6-HE3-08 is a dual common anode silicon planar Zener diode array from the Vishay AZ23 series, housed in an SOT-23 package. It features a nominal Zener voltage of 3.6 V with a tight tolerance of ±2%. The device is AEC-Q101 qualified for automotive applications and offers high ESD protection exceeding 8 kV (HBM) and 800 V (MM). Electrical characteristics include a maximum reverse leakage current of 1 µA at 1 V and a dynamic resistance of 90 Ω at a test current of 5 mA.
Feature Summary
- Dual common anode configuration within a compact SOT-23 surface-mount package
- AEC-Q101 qualification ensuring compliance with automotive reliability standards
- High electrostatic discharge robustness exceeding 8 kV human body model limits
- Tight voltage tolerance of ±2% for precise reference applications
Applications
- Automotive electronic circuits requiring AEC-Q101 compliant components
- Precision voltage reference and regulation tasks
- Electrostatic discharge (ESD) protection networks
Procurement Notes
Verify component authenticity by cross-referencing the manufacturer's part number against official Vishay documentation. Confirm that the ordering suffix matches the required tape-and-reel packaging format. Ensure the specific batch meets RoHS compliance requirements as defined in the product material categorization guidelines before finalizing procurement orders.
Selection Notes
Select this variant when a dual common anode topology is required alongside strict ±2% voltage tolerance. The HE3_A suffix indicates AEC-Q101 qualification, making it suitable for automotive environments where standard commercial grade parts are insufficient. Verify that the 300 mW power dissipation rating on an FR-4 board aligns with the thermal design constraints of the target application.
Part Context
This component belongs to the Vishay AZ23 series of small signal Zener diodes. The series provides a wide range of voltages from 2.2 V to 75 V in both single and dual configurations. The 'B' designation specifies the tighter ±2% tolerance band compared to the standard ±5% 'C' grade, while the 'HE3_A' suffix denotes the automotive-grade, lead-free variant.

FAQ
What is the difference between the AZ23B3V6-HE3-08 and AZ23C3V6-HE3-08?
The primary difference is the voltage tolerance. The 'B' suffix indicates a ±2% tolerance, whereas the 'C' suffix indicates a standard ±5% tolerance. Both share the same AEC-Q101 qualification and physical package.
Does the AZ23B3V6-HE3-08 support automotive applications?
Yes, the 'HE3_A' ordering suffix explicitly denotes that the device is AEC-Q101 qualified, meeting the reliability standards required for automotive electronics.
What is the maximum operating temperature for this device?
The device supports an operating temperature range from -55 °C to +150 °C, allowing for use in high-temperature industrial and automotive environments.
