BZX38450-C2V2F

Single Zener Diodes Overview

The Nexperia BZX38450-C2V2F is a low-current voltage regulator diode housed in an SOD-323 (SC-76) surface-mount package. It provides a nominal Zener voltage of 2.2 V with ±5% tolerance, tested at 50 μA. Key electrical parameters include a maximum total power dissipation of 300 mW, a forward voltage of 0.9 V at 10 mA, and a non-repetitive peak reverse power dissipation of 40 W. The device operates within a junction temperature range of -55 °C to +150 °C.

Single Zener Diodes Feature Summary

• Designed for low bias and portable battery-powered applications due to specification at a low test current of 50 μA.
• Features an intentional minor rise of leakage current to optimize fast switching and noise reduction.
• Encapsulated in a small SOD-323 plastic package suitable for high-density circuit designs.

Single Zener Diodes Applications

• Low-current general regulation functions
• Portable battery-powered applications

Single Zener Diodes Procurement Notes

Verify the specific suffix 'F' against official Nexperia documentation to confirm reel packaging details, as standard datasheets may not explicitly define all tape-and-reel variations. Ensure the component matches the BZX38450 series specifications for the C-tolerance variant. Cross-reference the marking code '6T' on the physical device to validate authenticity and correct voltage rating before integration into production.

Single Zener Diodes Selection Notes

Select this component for circuits requiring precise low-voltage regulation with minimal quiescent current consumption. The ±5% tolerance suits general-purpose applications where tight precision is not critical. Consider the thermal resistance characteristics when designing for high ambient temperatures or limited PCB copper area to ensure operation remains within the specified junction temperature limits.

Single Zener Diodes Part Context

This part belongs to the BZX38450 series of low-power voltage regulator diodes from Nexperia. The series offers a wide working voltage range from 1.8 V to 51 V in a compact SMD footprint. It is distinct from higher-power series like BZX585 or BZV90, focusing specifically on low-current efficiency and small form factor requirements for modern electronic devices.

Single Zener Diodes Replacement Considerations

Direct substitutes within the same series include BZX38450-C2V2. Verify compatibility with other manufacturers' SOD-323 Zener diodes having identical 2.2 V nominal voltage and similar power dissipation ratings if sourcing alternatives.
