DZ23C22-7

Overview

The DZ23C22-7 is a dual surface mount Zener diode manufactured by Diodes Incorporated. It features two Zener diodes in a common cathode configuration within an SOT-23 package. The nominal Zener voltage is 22 V, with a range of 20.8 V to 23.3 V at a test current of 5.0 mA. Maximum Zener impedance is 55 Ω at IZT = 5.0 mA and 220 Ω at IZK = 1.0 mA. The device has a power dissipation rating of 300 mW and a thermal resistance (junction to ambient) of 417 °C/W. Operating temperature ranges from -65°C to +150°C.

Feature Summary

• Dual Zeners in Common Cathode Configuration
• Ideally Suited for Automated Insertion
• Totally Lead-Free & Fully RoHS Compliant

Applications

• Voltage regulation circuits
• Automated insertion processes
• High reliability applications

Procurement Notes

Verify the exact part number against the manufacturer's datasheet DS18002 Rev. 22-2. Confirm that the commercial grade qualification matches your design requirements, as automotive versions require specific Q-suffix ordering. Ensure compliance with RoHS and lead-free specifications if required by your assembly process.

Selection Notes

Select this component when a dual Zener array in a compact SOT-23 package is needed. The common cathode configuration simplifies circuit layout compared to discrete components. Consider the 300mW power dissipation limit and the 5% tolerance on Zener voltage matching between the two diodes within the same case.

Part Context

This part belongs to the DZ23C series of 300mW dual surface mount Zener diodes produced by Diodes Incorporated. The series covers a wide range of Zener voltages from 2.7V to 51V. The DZ23C22-7 specifically provides a 22V reference point within this lineup, sharing the same mechanical and electrical characteristics as other members of the family.

Replacement Considerations

For automotive applications requiring AEC-Q100/101/200 qualification, refer to the related automotive grade parts with the Q-suffix. For common anode configurations, see the AZ23 series.
