Overview
The DZ23C27HE3-TP is a dual Zener diode in a common cathode configuration, housed in an SOT-23 package. It provides a nominal Zener voltage of 27V with a test current (IZT) of 5.0mA and a maximum impedance (ZZT) of 80Ω at this current. The device supports a total power dissipation of 300mW and operates within a junction temperature range of -55°C to +150°C. Thermal resistance from junction to ambient is rated at 417°C/W. The component is AEC-Q101 qualified, RoHS compliant, and features matched Zener voltages between the two internal diodes with a deviation of ≤5%.
Feature Summary
- Dual Zener diodes integrated in a single common cathode package for space-efficient circuit design.
- Automotive-grade qualification ensuring reliability under rigorous environmental conditions.
- Matched voltage characteristics between both diodes to ensure consistent performance.
- Halogen-free construction meeting green device standards.
Applications
- Voltage reference circuits requiring dual independent references.
- Over-voltage protection stages in automotive electronic modules.
- Signal clamping applications in digital logic interfaces.
Procurement Notes
Verify authenticity by purchasing exclusively from Micro Commercial Components or their authorized distributors. Counterfeit components pose significant risks; unauthorized sources do not provide warranty coverage. Confirm that the ordering suffix indicates RoHS compliance and tape-and-reel packaging containing 3000 pieces per reel before finalizing procurement orders.
Selection Notes
Select this component when a compact dual Zener solution is required for automotive or industrial environments. Ensure the 27V nominal breakdown voltage aligns with the target circuit requirements. Verify that the 300mW power rating and 80Ω impedance are sufficient for the specific application's current and thermal constraints.
Part Context
This part belongs to the DZ23C series, which covers Zener voltages from 2.4V to 47V. All devices in this series share the same SOT-23 footprint and electrical characteristics structure, differing primarily in their specific Zener voltage ratings and corresponding marking codes.
Replacement Considerations
Direct replacements must match the SOT-23 package, 300mW power rating, and dual common cathode configuration. Verify that substitute parts meet AEC-Q101 automotive qualification standards if used in vehicle applications.
