Overview
The DZ23B5V6-HE3-08 is a dual common cathode Zener diode manufactured by Vishay Semiconductors. It features a nominal Zener voltage of 5.6 V with a 2% tolerance and a maximum power dissipation of 300 mW. The device operates within a temperature range of -55°C to +150°C and carries AEC-Q101 automotive qualification. Packaged in an SOT-23-3 surface-mount case, it exhibits a maximum reverse leakage current of 1 µA and a Zener impedance of 60 Ohms at a test current of 5 mA.
Feature Summary
- Dual common cathode configuration for space-efficient circuit design
- Automotive-grade reliability certified under AEC-Q101 standards
- High thermal stability supporting operation up to 150°C
Applications
- Automotive voltage regulation circuits
- Signal clamping and protection stages
- Reference voltage generation in compact modules
Procurement Notes
Verify the specific datasheet revision and package marking codes before integration. Confirm that the AEC-Q101 qualification aligns with your project's automotive grade requirements. Ensure the SOT-23-3 footprint matches your PCB layout constraints. Cross-reference the electrical parameters against your system's worst-case operating conditions.
Selection Notes
Select this component when a dual Zener solution is required in a small surface-mount package. The 5.6 V nominal voltage suits standard logic level reference applications. The 2% tolerance provides tighter voltage control compared to standard 5% devices. Consider the 300 mW power rating for thermal management in dense layouts.
Part Context
This part belongs to the DZ23 series of dual Zener diodes from Vishay. The series offers various voltage combinations in the SOT-23-3 package. These components are designed for general-purpose and automotive electronics requiring reliable voltage referencing or clamping functions in minimal board space.
Replacement Considerations
Publicly confirmed substitute part numbers were not identified in the provided source material. Verify compatibility with alternative dual Zener diodes based on pinout, voltage tolerance, and power dissipation ratings.
