Overview
The DZ23C4V7HE3-TP is a dual Zener diode in a common cathode configuration, manufactured by Micro Commercial Components (MCC). It operates within a voltage range of 2.4 to 47 Volts and features a maximum power dissipation of 300 mW. The nominal Zener voltage is 4.7 V with a tolerance of ±5%. Key electrical parameters include a test current (IZT) of 5.0 mA, a maximum Zener impedance (ZZT) of 78 Ω at IZT, and a maximum reverse leakage current (IR) of 5.0 µA at 2.0 V. The device supports an operating junction temperature range from -55°C to +150°C and utilizes a SOT-23 surface-mount package.
Feature Summary
- Dual Zener diodes integrated in a single common cathode configuration for space-efficient circuit design.
- AEC-Q101 qualified for automotive reliability standards.
- Halogen-free "Green" device compliant with environmental regulations.
- Moisture Sensitivity Level 1 rated for robust handling during assembly.
Applications
- Automotive electronic systems requiring AEC-Q101 compliance.
- Voltage reference circuits utilizing dual independent channels.
- Over-voltage protection stages in industrial control equipment.
Procurement Notes
Verify authenticity through authorized MCC distributors or direct procurement to avoid counterfeit components. Confirm the specific suffix designation matches the required RoHS compliance and packaging format. Ensure storage conditions adhere to the specified moisture sensitivity level requirements prior to soldering.
Selection Notes
Select this component when a dual-channel voltage regulation solution is required in a compact SOT-23 footprint. The tight matching tolerance between the two internal diodes makes it suitable for differential applications. Verify that the 300 mW power rating and thermal resistance meet the specific ambient temperature constraints of the target application.
Part Context
This part belongs to the DZ23C series, which covers Zener voltages from 2.4 V to 47 V. All variants share identical physical dimensions and pin configurations, differing only in their electrical breakdown characteristics. The series is designed for automated insertion processes and general-purpose surface-mount applications.
Replacement Considerations
Direct substitutes must match the SOT-23-3 package, 300 mW power rating, and dual common cathode topology. Verify that alternative parts maintain equivalent AEC-Q101 qualification if used in automotive contexts. Cross-referencing requires checking specific Zener voltage tolerances and impedance values against the original datasheet specifications.
