Overview
The AZ23C20-HE3_A-08 is a silicon planar Zener diode array manufactured by Vishay General Semiconductor - Diodes Division. It features a common anode configuration with two diodes in a single SOT-23 package. The nominal Zener voltage is 20 V with a ±5% tolerance, tested at 5 mA. Key electrical parameters include a maximum reverse leakage current of 50 µA and a dynamic resistance (ZZ) of 50 Ω at the test current. The device is AEC-Q101 qualified for automotive applications and operates within a junction temperature range of -55 °C to +150 °C.
Feature Summary
- Dual Zener diodes integrated into a single common anode configuration for space-efficient circuit design.
- Qualified to AEC-Q101 standards for automotive reliability requirements.
- ESD protection capability exceeding 8 kV via human body model and 800 V via machine model.
Applications
- Automotive electronic circuits requiring dual voltage reference points.
- Clamping and protection stages in signal conditioning paths.
- Voltage regulation tasks in compact surface-mount assemblies.
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to confirm tape-and-reel specifications and quantity per reel. Ensure that the procurement channel sources components directly from authorized distributors to guarantee authenticity and traceability of the AEC-Q101 qualification status.
Selection Notes
Select this component when a dual-channel voltage reference or clamping solution is required in a minimal footprint. The HE3_A suffix indicates AEC-Q101 compliance, making it suitable for automotive environments where standard commercial grade parts may not meet reliability standards. Confirm that the 20 V nominal voltage aligns with the target circuit requirements.
Part Context
This part belongs to the AZ23 series of small signal Zener diodes from Vishay. The series offers a wide range of Zener voltages from 2.2 V to 75 V. The 'C' designation indicates a standard ±5% tolerance, while the 'HE3_A' suffix denotes RoHS compliance combined with AEC-Q101 automotive qualification.
