Overview
The DZ23C39HE3-TP is a dual Zener diode array manufactured by Micro Commercial Components (MCC) in an SOT-23 surface-mount package. It features a common cathode configuration with two independent Zener diodes housed in a single case. The nominal Zener voltage is 39 V, with a tolerance of ±5% for both diodes within the same package. Maximum power dissipation is rated at 300 mW, and the device operates within a junction temperature range of -55°C to +150°C. Electrical characteristics include a maximum Zener impedance of 90 Ohms at a test current of 5.0 mA and a maximum reverse leakage current of 0.1 µA at 29.0 V.
Feature Summary
- Dual Zener diodes integrated in a common cathode configuration within a compact SOT-23 package.
- Tight voltage matching between the two internal diodes, ensuring a differential of less than or equal to 5%.
- Qualified for automotive applications under the AEC-Q101 standard.
- Halogen-free construction compliant with green device requirements.
Applications
- Automotive electronic circuits requiring AEC-Q101 qualified components.
- Voltage reference generation for precision analog signal processing.
- Over-voltage protection stages in sensitive input/output interfaces.
Procurement Notes
Verify authenticity through authorized MCC distributors to avoid counterfeit parts. Confirm RoHS compliance via the 'P' suffix designation if required. Ensure storage conditions adhere to Moisture Sensitivity Level 1 standards. Check datasheet revisions for potential parameter updates before finalizing procurement specifications.
Selection Notes
Select this component when a matched pair of Zener diodes is required in a minimal footprint. The 39 V nominal voltage suits specific reference needs. Verify that the 300 mW power rating accommodates the expected thermal load. Consider the 90 Ohm impedance value for high-frequency response requirements.
Part Context
This part belongs to the DZ23C series, covering Zener voltages from 2.4 V to 47 V. All variants share the same SOT-23 physical dimensions and electrical structure, differing only in breakdown voltage. The HE3 suffix indicates Halogen-free epoxy meeting UL 94 V-0 flammability ratings.
Replacement Considerations
Direct substitutes must match the SOT-23-3 package, 300 mW power rating, and dual common cathode configuration. Verify that alternative parts meet AEC-Q101 qualification if automotive use is intended. Ensure voltage tolerance and impedance values are compatible with the circuit design.
