DZ23C24HE3-TP

Overview

The DZ23C24HE3-TP is a dual Zener diode in a common cathode configuration, housed in an SOT-23 package. It features a nominal Zener voltage of 24V with a tolerance range of 22.80V to 25.20V at a test current (IZT) of 5.0mA. The device has a maximum Zener impedance (ZZT) of 80Ω and a reverse leakage current (IR) of 0.1µA at 18.0V. Power dissipation is rated at 300mW, with a thermal resistance of 417°C/W from junction to ambient. Operating and storage temperatures span -55°C to +150°C.

Feature Summary

• Qualified for automotive applications under AEC-Q101 standards.
• Halogen-free "Green" device construction with UL 94 V-0 flammability rating epoxy.

Applications

• Automotive electronics requiring AEC-Q101 qualified components.
• Voltage reference circuits utilizing matched dual Zener pairs.
• Overvoltage protection stages in compact surface-mount assemblies.

Procurement Notes

Verify authenticity by purchasing only from Micro Commercial Components or their authorized distributors. Counterfeit parts are a known industry risk; unauthorized sources do not provide warranty coverage or traceability. Confirm the "TP" suffix indicates Tape & Reel packaging containing 3,000 pieces per reel. Ensure the specific part number matches the required voltage marking code KVO on the component body.

Selection Notes

Select this component when a dual Zener solution with tight voltage matching is required in an SOT-23 footprint. The 24V nominal voltage and 80Ω impedance suit low-current regulation tasks. Verify that the 300mW power dissipation and 417°C/W thermal resistance meet the thermal constraints of the target application environment.

Part Context

This part belongs to the DZ23C series, which covers Zener voltages from 2.4V to 47V in the SOT-23 package. All variants share identical physical dimensions and electrical characteristics except for the specific Zener voltage and corresponding impedance values. The series is designed for automated insertion and offers consistent performance across the voltage range.

Replacement Considerations

Direct substitutes must match the SOT-23 package, dual common cathode structure, 24V nominal voltage, and ≤5% delta VZ specification. Verify that any alternative component meets AEC-Q101 qualification if automotive use is intended. Check that thermal resistance and power dissipation ratings are equal to or exceed 417°C/W and 300mW respectively.

FAQ
