Overview
The DZ23C20HE3-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 device is housed in an SOT-23 package and is qualified under AEC-Q101 standards for automotive applications. Electrical specifications include a nominal Zener voltage of 20 V at a test current of 5.0 mA, with a maximum impedance of 50 Ω. The component supports an operating junction temperature range from -55°C to +150°C and utilizes lead-free finish compliant with RoHS directives.
Feature Summary
- Dual Zener diodes integrated in a single common cathode package
- AEC-Q101 qualification for automotive reliability
- Tight voltage matching between internal diodes
- Halogen-free green device construction
Applications
- Automotive instrument cluster protection
- Digital dashboard voltage regulation
- LED lighting circuit stabilization
Procurement Notes
Verify authenticity through authorized MCC distributors or direct purchase to avoid counterfeit components. Confirm the presence of the TP suffix indicates tape and reel packaging containing 3000 pieces per reel. Ensure compliance with UL 94 V-0 flammability ratings and moisture sensitivity level 1 requirements during storage and handling procedures.
Selection Notes
Select this component when dual independent voltage references are required in a compact surface-mount footprint. The tight tolerance between the two internal diodes makes it suitable for differential signaling or balanced protection circuits. Verify that the 300 mW power rating and 50 Ω impedance meet the specific load and noise requirements of the target application design.
Part Context
This part belongs to the DZ23C series, which encompasses various Zener voltage options from 2.4V to 47V. All variants share identical physical dimensions, thermal characteristics, and packaging formats. The series is designed for automated insertion processes and offers consistent performance across the entire voltage range within the same SOT-23 housing.
Replacement Considerations
Other parts within the DZ23C series may serve as functional substitutes if different voltage levels are acceptable. Cross-referencing pinout compatibility and thermal resistance values is essential when replacing with components from other manufacturers.
