Overview
The DZ23C3V9HE3-TP is a dual Zener diode array manufactured by Micro Commercial Components (MCC) in an SOT-23 package. It features two common cathode silicon Zener diodes with a nominal voltage of 3.9 V and a tolerance of ±5%. The device has a maximum power dissipation of 300 mW, a test current of 5.0 mA, and a maximum Zener impedance of 95 Ω at this current. It operates within a junction temperature range of -55°C to +150°C and is AEC-Q101 qualified for automotive applications.
Feature Summary
- Dual Zener diodes integrated into a single compact SOT-23 package
- AEC-Q101 qualification for automotive reliability standards
- Tight voltage matching between both diodes within the same case
- Halogen-free "Green" device construction
Applications
- Automotive electronic circuits requiring voltage regulation
- Voltage reference applications in portable devices
- Clamping and protection circuits in signal lines
Procurement Notes
Verify authenticity through authorized MCC distributors or direct purchase from Micro Commercial Components Corp. to avoid counterfeit parts. Confirm the specific HE3 suffix indicates RoHS compliance and halogen-free status as per the manufacturer's ordering information. Ensure the packaging matches the required tape and reel quantity for automated insertion processes.
Selection Notes
Select this component when a dual common cathode configuration is needed in a small surface-mount footprint. The 3.9 V nominal voltage and ±5% tolerance suit precise low-voltage regulation tasks. Consider the 300 mW power rating and thermal resistance of 417°C/W for heat dissipation requirements in the target application environment.
Part Context
This part belongs to the DZ23C series of dual Zener diodes ranging from 2.4 V to 47 V. All variants share the same SOT-23 package and electrical characteristics structure, differing primarily in their nominal Zener voltage values. The series is designed for automated assembly and meets strict environmental standards for modern electronics manufacturing.
Replacement Considerations
Direct substitutes include other DZ23C3V9 variants such as DZ23C3V9-TP if the HE3 suffix is not strictly required for environmental compliance. Verify that any replacement maintains the dual common cathode configuration, SOT-23 package, and AEC-Q101 qualification if automotive use is intended.
