AZ23C2V7 RFG

Overview

The AZ23C2V7 RFG is a dual common anode Zener diode array manufactured by Taiwan Semiconductor Corporation. It features two independent voltage regulator elements housed in a compact SOT-23 surface-mount package. The nominal Zener voltage is specified at 2.7 V with a tolerance of ±5%. The device supports a maximum power dissipation of 300 mW and operates within a junction temperature range of -55°C to +150°C. Key electrical characteristics include a maximum reverse leakage current of 20 µA at 1 V and a maximum Zener impedance of 100 Ohms, tested at a current of 5 mA.

Feature Summary

• Dual common anode configuration for space-efficient circuit design
• Compact SOT-23 surface-mount packaging suitable for automated assembly
• High thermal stability with extended operating temperature range

Applications

• Voltage reference circuits requiring stable low-voltage sources
• Clamping and protection stages in signal processing paths
• Biasing networks in portable electronic devices

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct packaging and compliance status. Confirm that the requested quantity aligns with standard reel or cut-tape availability constraints defined by the supplier. Cross-reference the component marking code with the datasheet to authenticate the source and prevent counterfeit substitution during acquisition.

Selection Notes

Select this component when a dual Zener solution with a common anode is required in a minimal footprint. Ensure the application voltage does not exceed the 2.7 V nominal rating under expected load conditions. Verify that the 300 mW power dissipation limit accommodates the thermal environment and duty cycle of the target system without exceeding the maximum junction temperature specification.

Part Context

This part belongs to the AZ23C series of small-signal Zener diode arrays from Taiwan Semiconductor. The series offers various voltage options within the same SOT-23 form factor, allowing designers to maintain consistent board layouts across different voltage requirements while utilizing identical footprints and assembly processes for manufacturing efficiency.

Replacement Considerations

Direct pin-compatible substitutes include the AZ23C2V7HE3-TP from Micro Commercial Components and the AZ23C2V7_R2_10001 from Panjit. Verify that alternative manufacturers meet the same 300 mW power rating and 2.7 V Zener voltage tolerance specifications before implementation.
