AZ23C6V2

Overview

The AZ23C6V2 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 two independent voltage regulator elements. The nominal Zener voltage is 6.2 V, with a range of 5.8 V to 6.6 V at a test current of 5 mA. Maximum power dissipation is 300 mW, and the junction temperature range spans from -55 °C to +150 °C. Electrical specifications include a maximum Zener impedance of 10 Ω at 5 mA and a maximum leakage current of 2.0 µA at 2.0 V reverse voltage.

Feature Summary

• Dual common anode configuration for space-efficient circuit design
• Halogen-free molding compound compliant with IEC standards
• Automated assembly suitability with Level 1 moisture sensitivity rating

Applications

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

Procurement Notes

Verify the specific ordering suffix (e.g., RFG) against the manufacturer's datasheet to confirm packaging details such as reel size and quantity per reel. Ensure the component meets RoHS compliance and halogen-free requirements if specified by the project constraints. Cross-reference the marking code KDA on the physical device to confirm authenticity and correct voltage variant.

Selection Notes

Select this component when a dual Zener array with a common anode is required in a compact SOT-23 footprint. The 6.2 V nominal voltage suits reference circuits operating within the 5.8 V to 6.6 V tolerance band. Consider the 300 mW power dissipation limit and thermal resistance of 420 °C/W for heat management in dense PCB layouts.

Part Context

This part belongs to the AZ23C series, which covers Zener voltages from 2.7 V to 51 V. All devices in this series share the same SOT-23 package and mechanical dimensions, differing primarily in their electrical characteristics and marking codes. The series is designed for general-purpose voltage regulation tasks in consumer and industrial electronics.

Replacement Considerations

Direct substitutes must match the SOT-23-3 package, dual common anode configuration, and 6.2 V nominal Zener voltage. Verify that alternative parts meet the 300 mW power dissipation and -55 °C to +150 °C operating temperature range. Check for equivalent leakage current and impedance specifications to ensure circuit performance parity.
