AZ23C8V2

Overview

The AZ23C8V2 is a dual surface-mount Zener diode manufactured by Taiwan Semiconductor Corporation, housed in an SOT-23 package. It features a common anode configuration with a nominal Zener voltage of 8.2 V and a range of 7.7 V to 8.7 V. The device supports a maximum power dissipation of 300 mW at 25°C ambient temperature, with a junction temperature range from -55°C to +150°C. Electrical characteristics include a Zener impedance (ZzT) of 7 Ω and a leakage current (Ir) of 1 µA at 6 V reverse voltage. The component meets RoHS compliance standards and is halogen-free.

Feature Summary

• Dual Zener diodes integrated in a single common anode configuration for space-efficient circuit design
• Qualified for automated assembly processes with Level 1 moisture sensitivity rating per J-STD-020
• Constructed with UL 94V-0 rated molded plastic compound and matte tin plated leads

Applications

• Low voltage stabilizers or voltage references
• Adapters
• Lighting applications
• On-board DC/DC converters

Procurement Notes

Verify the specific ordering suffix when sourcing this component, as variations such as 'RFG' indicate the use of green molding compound which affects material composition but not electrical function. Confirm that the received parts match the KDD marking code specified in the datasheet to ensure authenticity and correct voltage tolerance. Check for RoHS compliance documentation if required by your manufacturing standards.

Selection Notes

Select the AZ23C8V2 when a dual Zener solution with a common anode is required within the SOT-23 footprint. Ensure the application voltage does not exceed the 300 mW power dissipation limit at the expected operating temperature. Consider the 7 Ω Zener impedance for noise-sensitive circuits and verify that the 1 µA leakage current meets the requirements for high-impedance reference nodes.

Part Context

This component belongs to the AZ23C series, which covers a wide Zener voltage range from 2.7 V to 51 V. All devices in this family share the same SOT-23 mechanical outline and thermal characteristics, allowing for standardized PCB layouts across different voltage requirements. The series is designed for general-purpose voltage regulation tasks in consumer and industrial electronics.

Replacement Considerations

Cross-reference with other manufacturers offering dual Zener diodes in SOT-23 packages with common anode configurations. Verify that substitute components meet the 300 mW power rating and 8.2 V nominal voltage specifications. Ensure the replacement part has compatible thermal resistance and leakage current characteristics for the intended application.
