AZ23B10-G3-18

Overview

The AZ23B10-G3-18 is a dual common anode silicon planar Zener diode array manufactured by Vishay General Semiconductor - Diodes Division. It features a nominal Zener voltage of 10 V with a tight tolerance of ±2%, tested at a current of 5 mA. The device operates within a temperature range of -55 °C to +150 °C and dissipates up to 300 mW on an FR-4 board. Packaged in a compact SOT-23 (TO-236AB) surface-mount housing, it utilizes the 'G3' suffix for lead-free, halogen-free compliance.

Feature Summary

• Dual common anode configuration providing two independent Zener references in a single package
• High precision grading with ±2% Zener voltage tolerance for accurate reference applications
• Lead-free construction compliant with RoHS directives and material categorization standards

Applications

• Precision voltage reference circuits requiring dual polarity or split-rail supplies
• Over-voltage protection stages utilizing the common anode topology
• Signal conditioning and clamping networks in industrial control systems

Procurement Notes

Verify the specific ordering code against the manufacturer's official documentation to ensure correct tolerance and packaging specifications. Confirm that the component meets all required environmental and regulatory standards for the intended application before finalizing procurement orders.

Selection Notes

Select this component when a dual Zener array with high voltage accuracy is required in a small footprint. Ensure the design accounts for the 300 mW power dissipation limit on standard PCBs and verify that the 10 V breakdown voltage aligns with the circuit's operational requirements.

Part Context

This part belongs to the AZ23-G series of small signal Zener diodes from Vishay. The series offers a wide range of standardized voltages from 2.2 V to 75 V. The 'B' designation indicates the tighter ±2% tolerance grade compared to the standard ±5% 'C' grade devices.

Replacement Considerations

Direct replacements include other AZ23B10 variants such as AZ23B10-E3-18 or AZ23B10-G3-08, provided the tape-and-reel quantity matches the production needs. Cross-brand equivalents must be verified for identical pinout, voltage tolerance, and thermal characteristics.
