BZT5250H-B5V1X

Single Zener Diodes Overview

The BZT5250H-B5V1X is a low-current voltage regulator diode from the Nexperia BZT5250H series, housed in an SOD123F surface-mounted plastic package. It features a nominal working voltage of 5.1 V with ±2% tolerance (B series). The device is specified at a low test current of 50 μA, making it suitable for low bias applications. Key electrical parameters include a maximum differential resistance of 60 Ω at IZ = 50 μA and a reverse current of up to 3.7 μA at IZ = 5 mA. Total power dissipation reaches 830 mW.

Single Zener Diodes Feature Summary

• Designed for low-current general regulation functions with specifications optimized for low bias conditions.
• Features an intentional minor rise in leakage current within the B-series range to support fast switching and noise reduction.
• Utilizes a small, flat-lead SMD plastic package suitable for high-density surface-mounted designs.

Single Zener Diodes Applications

• Low-current general regulation functions
• Portable battery-powered applications requiring low bias operation

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct tolerance and packaging configuration. Confirm that the component meets all relevant environmental compliance standards required for the target application before finalizing procurement decisions.

Single Zener Diodes Selection Notes

Select this component when precise voltage regulation is needed under low current conditions. The B-series offers tighter tolerance compared to the C-series. Ensure the design accounts for the specified test current of 50 μA to maintain accuracy in low-power portable systems.

Single Zener Diodes Part Context

This part belongs to the BZT5250H series of general-purpose Zener diodes manufactured by Nexperia. The series provides a wide range of nominal voltages from 1.8 V to 51 V in the E24 range, packaged in the compact SOD123F format for efficient PCB layout.

Single Zener Diodes Replacement Considerations

Direct substitutes within the same series include BZT5250H-C5V1X, which shares the same package but has approximately ±5% tolerance. Other series members like BZT5250H-B5V6X are available for different voltage requirements.
