DZ23C3V3HE3-TP

Overview

The DZ23C3V3HE3-TP is a dual Zener diode in common cathode configuration, manufactured by Micro Commercial Components (MCC). It provides a nominal Zener voltage of 3.3 V with a tolerance range of 3.14 V to 3.47 V at a test current of 5.0 mA. The device features a maximum Zener impedance of 95 Ω and a maximum reverse leakage current of 25 µA at 1.0 V. Rated for 300 mW power dissipation, it operates within a junction temperature range of -55°C to +150°C. Packaged in an SOT-23 surface-mount case, the component is AEC-Q101 qualified and designed for automated insertion.

Feature Summary

• Dual Zener diodes integrated into a single compact SOT-23 package
• Tight voltage matching between internal diodes with delta Vz ≤5%
• Automotive-grade qualification compliant with AEC-Q101 standards
• Halogen-free construction with UL 94 V-0 flammability rating

Applications

• Automotive electronic circuit protection
• Industrial application voltage regulation
• Automated surface-mount assembly processes

Procurement Notes

Verify authenticity through authorized MCC distributors or direct purchase from Micro Commercial Components Corp. to ensure full traceability and compliance with quality standards. Counterfeit parts lack warranty coverage. Confirm specific ordering suffixes match required packaging configurations before procurement.

Selection Notes

Select this component when dual independent Zener references are required in a minimal footprint. Ensure the 3.3 V nominal breakdown aligns with circuit requirements. Verify that the 300 mW power rating accommodates expected thermal loads within the specified operating temperature range.

Part Context

This part belongs to the DZ23C series covering voltages from 2.4 V to 47 V. All variants share identical physical dimensions and electrical characteristics except for the specific Zener voltage ratings. The series utilizes standardized SOT-23 packaging suitable for high-volume manufacturing environments.

Replacement Considerations

Direct substitutes include other DZ23C3V3HE3-TP units from different authorized sources. Cross-referencing requires verifying identical pinout, voltage tolerance, and package dimensions.
