Overview
The AZ23B6V8-E3-08 is a dual common anode silicon planar Zener diode array from Vishay, housed in a SOT-23 surface-mount package. It features a nominal Zener voltage of 6.8 V with a tight tolerance of ±2%. The device operates at a test current of 5 mA and dissipates up to 300 mW on an FR-4 board. Electrical characteristics include a maximum reverse leakage current of 1 µA and a dynamic resistance of 8 Ω. It supports an operating temperature range from -55 °C to +150 °C.
Feature Summary
- Dual common anode configuration for space-efficient circuit designs
- High ESD protection capability exceeding 8 kV via human body model
- RoHS-compliant commercial grade construction
Applications
- Voltage reference circuits requiring precise dual rails
- ESD protection stages in signal conditioning paths
- Clamping applications in low-power consumer electronics
Procurement Notes
Verify the specific suffix 'E3' confirms RoHS compliance and lead-free status. Confirm the '-08' suffix indicates the standard 3000-unit reel packaging format. Ensure the 'B' designation matches the required ±2% voltage tolerance for the application.
Selection Notes
Select this component when a dual Zener array with high precision (±2%) is required in a compact SOT-23 footprint. Consider the 300 mW power dissipation limit on FR-4 boards and the specific 6.8 V breakdown voltage. Verify that the common anode topology aligns with the circuit schematic requirements.
Part Context
This part belongs to the AZ23 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series offers various voltage grades and tolerances within the same SOT-23 package family, allowing for design flexibility while maintaining consistent physical dimensions and thermal characteristics across different voltage options.
