DZ23C2V2-HE3_A-08

Overview

The Vishay DZ23C2V2-HE3_A-08 is a dual common cathode Zener diode housed in an SOT-23-3 surface-mount package. It features a nominal Zener voltage of 2.2 V with a 5% tolerance and a maximum power dissipation of 300 mW. The device exhibits a low reverse leakage current of 100 nA and a Zener impedance of 100 Ohms at the test current. It operates within a temperature range of -55 °C to +150 °C, ensuring stability across industrial environments.

Feature Summary

• Dual common cathode configuration for space-efficient circuit design
• Low leakage current characteristics for high-impedance applications
• Robust thermal performance with extended operating temperature range

Applications

• Voltage reference circuits requiring precise low-voltage regulation
• Clamping and protection stages in signal processing paths
• Biasing networks in analog integrated circuits

Procurement Notes

Verify the specific suffix HE3_A-08 against manufacturer documentation to confirm lead-free compliance and tape-and-reel specifications. Cross-reference the part number with official Vishay databases to ensure availability status and confirm that no obsolete notices apply before finalizing procurement plans.

Selection Notes

Select this component when a dual Zener structure is required in a compact SOT-23 footprint. Ensure the 2.2 V breakdown voltage aligns with the target circuit requirements. Verify that the 300 mW power rating suffices for the expected thermal conditions and that the 100 Ohm impedance meets the noise and regulation constraints of the application.

Part Context

This part belongs to the Vishay DZ23 series of dual Zener diodes designed for surface-mount assembly. The series offers various voltage options within the same SOT-23-3 package, facilitating standardized inventory management. The HE3 designation indicates a green mold compound compliant with RoHS directives, supporting environmentally conscious manufacturing processes.

Replacement Considerations

Direct replacements include other Vishay DZ23 series variants with matching voltage ratings. Alternative manufacturers offering SOT-23-3 dual common cathode Zeners with similar 2.2 V specifications may be considered if pinout compatibility and electrical parameters are verified.
