AZ23C3V9 RFG

Overview

The AZ23C3V9 RFG is a small signal Zener diode array manufactured by Taiwan Semiconductor Corporation. It features a dual common anode configuration housed in an SOT-23-3 surface-mount package. The device provides a nominal Zener voltage of 3.9 V with a tolerance of ±5%. It supports a maximum power dissipation of 300 mW and operates within a temperature range of -55°C to +150°C junction temperature. Key electrical characteristics include a maximum reverse leakage current of 100 nA, a Zener impedance of 95 Ohms at a test current of 5 mA, and compliance with RoHS standards.

Feature Summary

• Dual Zener diodes integrated into a single compact SOT-23-3 package for space-efficient circuit design.
• Common anode configuration simplifies biasing requirements in low-voltage regulation applications.
• High thermal stability with a maximum junction temperature rating of +150°C.

Applications

• Voltage reference circuits requiring stable low-voltage sources.
• Clamping and protection stages in portable electronic devices.
• Signal conditioning modules in industrial control systems.

Procurement Notes

Verify the complete part number including the RFG suffix to ensure correct packaging specifications. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Cross-reference datasheet parameters against specific application requirements to validate performance under expected operating conditions.

Selection Notes

Select this component when a dual Zener array with common anode topology is required in an SOT-23 form factor. Ensure the 3.9 V nominal voltage aligns with circuit design targets. Verify that the 300 mW power dissipation limit accommodates the thermal environment of the final assembly without exceeding junction temperature constraints.

Part Context

This component belongs to the AZ23C series of dual Zener diode arrays from Taiwan Semiconductor. The series offers various voltage options within the same SOT-23 footprint, facilitating standardized inventory management. The RFG suffix typically denotes specific tape-and-reel packaging configurations used in automated surface-mount assembly processes.

Replacement Considerations

Equivalent parts include Vishay Semiconductors AZ23C3V6-G3-08 and Panjit International AZ23C3V9_R2_00001. Verify pinout compatibility and exact voltage tolerances before substitution. Confirm that alternative manufacturers meet the same thermal and electrical specifications for direct replacement.
