AZ23B22-E3-08

Overview

The AZ23B22-E3-08 is a dual common-anode silicon planar Zener diode array manufactured by Vishay General Semiconductor - Diodes Division. It provides two independent voltage regulation channels within a single SOT-23 surface-mount package. The nominal Zener voltage is 22 V with a tight tolerance of ±2%, tested at a current of 5 mA. The device features a maximum power dissipation of 300 mW on an FR-4 board and operates across a temperature range of -55°C to +150°C. It complies with RoHS standards and utilizes the E24 grading standard for voltage selection.

Feature Summary

• Dual-channel configuration in a compact SOT-23-3 footprint
• High precision voltage regulation with ±2% tolerance
• Robust thermal performance up to 150°C junction temperature
• Lead-free construction compliant with international environmental directives

Applications

• Precision voltage reference circuits requiring dual rails
• Over-voltage protection for sensitive analog inputs
• Signal conditioning and clamping in communication equipment
• Power supply monitoring and threshold detection systems

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm that the ordering suffix matches the required tape-and-reel quantity and packaging specifications. Ensure compliance with project-specific material declarations and environmental regulations prior to integration into manufacturing processes.

Selection Notes

Select this variant when precise dual-channel regulation is required without occupying excessive board space. The ±2% tolerance makes it suitable for applications demanding tighter voltage accuracy than standard commercial grades. Consider the common-anode topology for shared ground reference designs.

Part Context

This component belongs to the AZ23 series of small signal Zener diodes, designed for general-purpose voltage regulation tasks. The 'B' designation indicates the tighter ±2% tolerance grade compared to the standard 'C' grade. The 'E3' suffix denotes lead-free termination, while '08' specifies the 3000-unit reel packaging format.

Replacement Considerations

AZ23C22-E3-08 offers identical physical dimensions but with reduced ±5% voltage tolerance. AZ23B22-G3-08 provides equivalent electrical characteristics with different packaging or marking variations. Verify pinout compatibility and thermal resistance requirements before substituting.
