Overview
The AZ23B5V6-HE3-08 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 5.6 V with a tight ±2 % tolerance and operates at a test current of 5 mA. The device is AEC-Q101 qualified for automotive reliability and offers high ESD protection exceeding 8 kV (HBM) and 800 V (MM). Electrical characteristics include a maximum reverse leakage current of 1 μA and a dynamic resistance of 40 Ω at 5 mA.
Feature Summary
- Dual common anode configuration within a compact SOT-23 surface-mount package
- AEC-Q101 qualified for automotive-grade reliability standards
- High electrostatic discharge robustness exceeding 8 kV human body model limits
Applications
- Automotive voltage regulation circuits requiring AEC-Q101 compliance
- ESD protection stages in sensitive signal lines
- Reference voltage generation in low-power electronic systems
Procurement Notes
Verify component authenticity through authorized distribution channels to ensure compliance with Vishay specifications. Confirm that the ordering suffix matches the required tolerance and qualification level. Validate RoHS3 compliance status prior to integration into production workflows.
Selection Notes
Select this variant when a precise 5.6 V reference with ±2 % tolerance is required in a dual-channel layout. Ensure the application supports the 5 mA test current condition for optimal voltage accuracy. Verify thermal management capabilities against the specified junction-to-lead thermal resistance values.
Part Context
This part belongs to the AZ23 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series provides a wide range of graded voltages from 2.2 V to 75 V in standard E24 increments. The 'B' designation indicates the tighter ±2 % voltage tolerance compared to the standard ±5 % 'C' grade.
Replacement Considerations
AZ23B5V6-E3-08: Commercial grade equivalent without automotive qualification. AZ23B5V6-HE3_A-08: Alternative HE3 packaging variant within the same electrical specification family.
