Overview
The DZ23C33HE3-TP is a dual Zener diode in a common cathode configuration, housed in an SOT-23 package. It provides two independent 33V Zener channels within a single component. The device operates with a maximum power dissipation of 300mW and supports junction temperatures from -55°C to +150°C. Electrical specifications include a nominal Zener voltage of 33V at a test current of 5.0mA, with a maximum impedance of 80Ω. The unit features a thermal resistance of 417°C/W and meets AEC-Q101 automotive qualification standards.
Feature Summary
- Dual Zener diodes integrated in a common cathode configuration for space-saving designs
- Automotive-grade reliability through AEC-Q101 qualification
- Tight voltage matching between the two internal diodes with delta V-Z less than or equal to 5%
- Halogen-free construction with UL 94 V-0 flammability rating
Applications
- Automotive instrument cluster signal conditioning
- Digital dashboard overvoltage protection circuits
- Multi-channel voltage reference applications requiring matched characteristics
Procurement Notes
Verify authenticity by purchasing directly from Micro Commercial Components or authorized distributors. Counterfeit prevention measures are strictly enforced. Ensure the ordering suffix matches the required packaging format. Confirm RoHS compliance status before integration into regulated assemblies.
Selection Notes
Select this component when dual isolated Zener references are needed in a compact surface-mount footprint. The tight voltage tolerance makes it suitable for precision differential sensing. Verify that the 300mW power rating accommodates the expected operating current and ambient temperature conditions.
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 2.4V to 47V. All variants share the same SOT-23 physical dimensions and electrical testing parameters, differing only in their specific breakdown voltage ratings.
Replacement Considerations
Compatible substitutes include other dual Zener diodes in SOT-23 packages with similar power ratings. Verify pinout compatibility and ensure the replacement offers equivalent AEC-Q101 certification if used in automotive environments.
FAQ
What is the maximum reverse leakage current for the DZ23C33HE3-TP?
The maximum reverse current (IR) is specified as 0.1µA at a reverse voltage (VR) of 25.0V.
How does the device handle high-temperature operation?
The device supports an operating junction temperature range up to +150°C, though power dissipation must be derated according to the provided thermal curve.
Is the epoxy material flame retardant?
Yes, the epoxy meets the UL 94 V-0 flammability rating standard.
