Overview
The AZ23C5V6-HE3_A-08 is a silicon planar Zener diode array from the Vishay AZ23 series, housed in an SOT-23 package. It features a common anode configuration with two independent diodes sharing a single terminal. The nominal Zener voltage is 5.6 V with a tolerance of ±5%, tested at a current of 5 mA. Maximum reverse leakage current is specified as 1 µA at 4 V and 0.1 µA at 5 V. Dynamic resistance is limited to 40 Ω at 2 mA and 400 Ω at 1 mA. The device operates within a temperature range of -55 °C to +150 °C and is AEC-Q101 qualified.
Feature Summary
- Dual Zener diodes integrated into a single common anode structure for space-efficient circuit design
- AEC-Q101 automotive qualification ensuring reliability under rigorous environmental conditions
- ESD protection capability exceeding 8 kV via human body model and 800 V via machine model
Applications
- Automotive electronic circuits requiring robust ESD protection and voltage regulation
- Signal conditioning and clamping applications in consumer electronics
- Reference voltage generation in low-power portable devices
Procurement Notes
Verify component authenticity by cross-referencing the ordering code against official Vishay documentation. Confirm that the HE3_A suffix corresponds to AEC-Q101 qualification and RoHS compliance. Ensure storage and handling procedures adhere to MSL level 1 standards to prevent moisture-induced damage during soldering processes.
Selection Notes
Select this component when a dual Zener array with a common anode topology is required. The 5.6 V nominal voltage suits applications needing precise reference levels or overvoltage protection near standard logic thresholds. Verify that the 5% tolerance meets the specific circuit requirements before finalizing the design.
Part Context
This part belongs to the AZ23 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series offers a wide range of Zener voltages from 2.2 V to 75 V in the SOT-23 package. The HE3_A variant specifically denotes automotive-grade qualification, distinguishing it from commercial grade E3 versions.
