AZ23C30-7-G

Overview

The AZ23C30-7-G is a dual common anode Zener diode array manufactured by Diodes Incorporated. It features two independent Zener diodes sharing a single anode terminal within a compact SOT-23 surface-mount package. The nominal Zener voltage is specified at 30 V with a tolerance of ±5%. The device has a maximum power dissipation of 300 mW and a Zener impedance of 80 Ohms at a test current of 5 mA. It operates reliably across a temperature range from -65°C to +150°C.

Feature Summary

• Dual common anode configuration for space-efficient circuit design
• High thermal stability suitable for demanding environments
• Compact SOT-23 footprint for automated surface-mount assembly

Applications

• Voltage reference circuits requiring dual stable potentials
• Transient voltage suppression in signal lines
• Clamping applications in portable electronic devices

Procurement Notes

This component is officially obsolete and no longer in production. Verification of availability should focus on surplus distributors or secondary markets rather than authorized supply chains. Engineers must confirm the authenticity of sourced units through rigorous testing, as obsolescence increases the risk of counterfeit components entering the market.

Selection Notes

Designers replacing this part should evaluate alternative dual Zener arrays with compatible pinouts and electrical characteristics. Key parameters to match include the 30 V nominal voltage, 300 mW power rating, and SOT-23 package dimensions. Ensure that any substitute meets the required operating temperature range and impedance specifications for the specific application context.

Part Context

The AZ23C30-7-G belongs to the AZ23C series of dual Zener diode arrays from Diodes Incorporated. This series is designed for general-purpose voltage regulation and protection tasks. The 'G' suffix typically indicates compliance with specific environmental standards, though the product status remains discontinued regardless of packaging variations.

Replacement Considerations

Direct replacement options include the AZ23C30-7-F variant from Diodes Incorporated. Other manufacturers offer equivalent SOT-23 dual Zener arrays with similar 30 V ratings. Verify pin compatibility and thermal performance before integrating substitutes into existing designs.
