BZT5250H-B39X

Single Zener Diodes Overview

The Nexperia BZT5250H-B39X is a low-current voltage regulator diode in the SOD123F surface-mount package. It features a nominal Zener voltage of 39 V with ±2% tolerance, specified at a test current of 50 µA. The device supports a total power dissipation up to 830 mW and operates within a junction temperature range of -55 °C to +150 °C. Key electrical characteristics include a maximum differential resistance of 350 Ω and a reverse leakage current of 41.2 µA at 2 mA test current.

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 and flat lead plastic package suitable for surface-mounted design.

Single Zener Diodes Applications

• Low-current general regulation functions

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging configuration. Ensure compliance with RoHS and REACH regulations as stated in the product data sheet. Confirm that the component meets the required thermal and electrical specifications for the intended operating environment before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component for circuits requiring precise voltage regulation under low-current conditions. The ±2% tolerance series offers tighter voltage accuracy compared to standard options. Consider the low test current specification when designing bias networks for battery-operated devices to minimize power consumption.
