AZ23B2V4-G3-08

Overview

The Vishay AZ23B2V4-G3-08 is a silicon planar Zener diode array in a SOT-23 package, configured as dual common anode. It provides a nominal Zener voltage of 2.4 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. Key electrical characteristics include a maximum reverse leakage current of 50 µA and a dynamic resistance of 100 Ω at the test current.

Feature Summary

• Dual common anode configuration for compact circuit integration
• Tight ±2% Zener voltage tolerance for precision applications
• High ESD protection capability exceeding 8 kV (HBM) and 800 V (MM)
• Lead-free construction compliant with RoHS standards

Applications

• Precision voltage reference circuits
• ESD protection for sensitive signal lines
• Voltage clamping in low-voltage logic interfaces

Procurement Notes

Verify the specific ordering code suffix against the manufacturer's latest documentation to confirm reel size and tape specifications. Confirm that the component meets the required environmental compliance standards for the intended deployment region before finalizing procurement orders.

Selection Notes

Select this part when a dual Zener configuration with high voltage accuracy is required in a small surface-mount footprint. Ensure the application current does not exceed the 5 mA test current limit to maintain the specified ±2% tolerance and prevent thermal drift beyond the rated operating temperature range.

Part Context

This component belongs to the AZ23-G series of small signal Zener diodes manufactured by Vishay Semiconductors. The series offers a wide range of standard Zener voltages from 2.2 V to 75 V, utilizing the E24 grading standard. The 'B' designation specifically indicates the tighter ±2% tolerance variant within this product family.

Replacement Considerations

Direct replacements must match the SOT-23-3 package, dual common anode configuration, and 2.4 V nominal voltage. Verify that any substitute component maintains the ±2% tolerance and similar dynamic resistance characteristics to ensure circuit performance parity.
