Overview
The DZ23C28HE3-TP is a dual Zener diode in a common cathode configuration, housed in an SOT-23 package. It features a total power dissipation of 300 mW and operates within a junction temperature range of -55°C to +150°C. The nominal Zener voltage is 28 V with a tolerance of ±5%, ranging from 26.60 V to 29.40 V at a test current of 5.0 mA. Maximum Zener impedance is 80 Ω at the test current and 300 Ω at a knee current of 1.0 mA. Reverse leakage current is limited to 0.1 µA at 22.0 V. The device is AEC-Q101 qualified and supplied in tape and reel packaging.
Feature Summary
- Dual Zener diodes integrated in a single common cathode package for space-efficient circuit design.
- Automotive-grade qualification ensuring reliability under harsh thermal conditions.
- Tight voltage matching between the two internal diodes to maintain balanced performance.
Applications
- Automotive electronic systems requiring robust voltage regulation.
- Industrial control circuits needing compact protection solutions.
- Signal conditioning stages utilizing matched dual reference voltages.
Procurement Notes
Verify authenticity through authorized MCC distributors to avoid counterfeit components. Confirm RoHS compliance and lead-free finish specifications during ordering. Ensure storage conditions adhere to moisture sensitivity level 1 requirements. Check for specific marking codes corresponding to the 28 V variant before finalizing procurement.
Selection Notes
Select this component when a dual Zener solution with matched voltage characteristics is required in a small surface-mount footprint. The 300 mW power rating supports moderate current applications. Verify that the 28 V nominal voltage aligns with the target circuit's regulation needs. Consider the 80 Ω impedance for dynamic load variations.
Part Context
This part belongs to the DZ23C series of dual Zener diodes manufactured by Micro Commercial Components. The series covers a wide voltage range from 2.4 V to 47 V. All variants share the same SOT-23 package and electrical structure, differing primarily in their specific Zener voltage ratings and associated marking codes.
Replacement Considerations
Direct substitutes include other DZ23C28 variants from different manufacturers if pin compatibility and electrical parameters match. Ensure any replacement maintains the common cathode configuration and meets AEC-Q101 standards for automotive applications.
