BZX38450-C2V7X

Single Zener Diodes Overview

The Nexperia BZX38450-C2V7X is a low-current voltage regulator diode housed in an SOD323 (SC-76) surface-mount package. It features a nominal Zener voltage of 2.7 V with ±5% tolerance, tested at 50 μA. The device supports a total power dissipation of up to 300 mW and operates within a junction temperature range of -55 °C to +150 °C. Key electrical characteristics include a maximum differential resistance of 600 Ω at IZ=50 μA, a reverse current of 1.0 μA at IZ=5 mA, and a typical diode capacitance of 190 pF at 1 MHz.

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 optimized for fast switching and noise reduction.
• Utilizes a small plastic SMD package suitable for high-density circuit designs.

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix matches the required tolerance series and packaging configuration. Confirm that the component meets all applicable environmental compliance standards relevant to the target market. Ensure design reviews account for the specified thermal resistance values during PCB layout to maintain safe operating temperatures under load conditions.

Single Zener Diodes Selection Notes

Select this component for circuits requiring precise low-voltage regulation with minimal quiescent current draw. The C-series offers approximately ±5% tolerance, suitable for general-purpose applications where tight precision is not critical. Consider the low test current specification when designing bias networks to ensure accurate voltage reference performance.

Single Zener Diodes Part Context

This part belongs to the BZX38450 series of low-current voltage regulator diodes from Nexperia. The series provides a wide working voltage range from nominal 1.8 V to 51 V in a compact SOD323 package. It is engineered specifically for applications demanding low power consumption and efficient space utilization in modern electronic devices.

Single Zener Diodes Replacement Considerations

Direct substitutes within the same series include BZX38450-B2V7 for tighter tolerance requirements. Cross-family replacements should match the SOD323 footprint, 300 mW power rating, and 2.7 V Zener voltage specifications while verifying compatibility with the low-test-current operational profile.
