AZ23B2V4-E3-18

Overview

The Vishay AZ23B2V4-E3-18 is a silicon planar Zener diode array housed in an SOT-23 package. It features a dual common anode configuration with a nominal Zener voltage of 2.4 V and a tight tolerance of ±2%. The device operates at a test current of 5 mA, dissipates up to 300 mW on FR-4 boards, and withstands junction temperatures up to 150 °C. It exhibits low reverse leakage current (max 1 µA) and dynamic resistance of 100 Ω. The component complies with RoHS standards and is supplied in 10,000-unit reels.

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
• RoHS-compliant commercial grade construction

Applications

• Precision voltage reference circuits
• Overvoltage protection stages
• Signal conditioning networks

Procurement Notes

Verify the complete ordering code matches the required specifications. Confirm that the suffix indicates the correct tape-and-reel quantity and packaging format. Ensure the manufacturer designation aligns with project requirements before finalizing procurement orders.

Selection Notes

Select this variant when a precise 2.4 V reference is needed with strict tolerance limits. The dual common anode structure allows efficient use of board space compared to discrete components. Verify thermal management capabilities against the maximum power dissipation rating under expected operating conditions.

Part Context

This component belongs to the Vishay AZ23 series of small signal Zener diodes. The series offers various voltage grades following the E24 standard. The 'B' designation specifically denotes the tighter ±2% tolerance band available within this product family.

Replacement Considerations

AZ23B2V4-E3-08 provides identical electrical characteristics but utilizes 3,000-unit reels instead of 10,000-unit reels.
