Overview
The AZ23B3V3-HE3_A-08 is a dual common anode silicon planar Zener diode array from the Vishay AZ23 series, housed in a SOT-23 package. It features a nominal Zener voltage of 3.3 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 5 µA at 3 V and a dynamic resistance of 95 Ω at a test current of 5 mA.
Feature Summary
- Dual common anode configuration providing two independent Zener references within a single three-terminal surface-mount package.
- Automotive-grade qualification compliant with AEC-Q101 standards, ensuring reliability under rigorous environmental conditions.
- High electrostatic discharge robustness rated above 8 kV via human body model and 800 V via machine model testing.
Applications
- Voltage reference circuits requiring precise low-voltage regulation in automotive electronics.
- Input protection stages for sensitive logic interfaces utilizing the integrated common anode topology.
- Clamping applications in environments demanding high ESD immunity and stable breakdown voltages.
Procurement Notes
Verify that the ordering code suffix HE3_A-08 corresponds to the specific AEC-Q101 qualified variant rather than commercial grade. Confirm the tape and reel packaging specifications match the required manufacturing equipment before finalizing procurement orders.
Selection Notes
Select this component when a dual Zener array with a strict ±2% voltage tolerance is required for automotive designs. Ensure the application operates within the specified -55 °C to +150 °C temperature range and respects the 300 mW power dissipation limit on standard FR-4 boards.
Part Context
This part belongs to the AZ23 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series utilizes silicon planar technology and provides a wide range of standardized Zener voltages according to the E24 series, catering to diverse voltage regulation needs in compact surface-mount form factors.
