BZV55-B39,115

Single Zener Diodes Overview

The BZV55-B39,115 is a single Zener diode manufactured by Nexperia USA Inc., designed for surface-mount applications in LLDS (MiniMelf) packages. It features a nominal Zener voltage of 39 V with a tight tolerance of ±2%. The device supports a maximum power dissipation of 500 mW and operates within an extended temperature range from -65°C to +200°C. Key electrical characteristics include a maximum reverse leakage current of 50 nA at 27.3 V and a maximum Zener impedance of 45 Ohms. The component is RoHS compliant and classified under ECCN EAR99.

Single Zener Diodes Feature Summary

• Provides precise voltage regulation with ±2% tolerance for stable reference applications
• Utilizes hermetically sealed glass MiniMelf packaging for high-density circuit designs
• Supports operation across a wide industrial temperature range up to 200°C

Single Zener Diodes Applications

• General voltage regulation circuits
• Voltage reference functions
• Over-voltage protection

Single Zener Diodes Procurement Notes

Verify the specific suffix '115' corresponds to the standard tape-and-reel packaging configuration as defined by Nexperia. Confirm that the ±2% tolerance designation ('B') aligns with the required precision for the target application. Ensure compatibility with SOD-80C footprint requirements during PCB layout. Cross-reference the latest datasheet for any potential package or labeling changes documented in recent Product Change Notices.

Single Zener Diodes Selection Notes

Select this component when a 39 V reference requires tighter than ±5% accuracy. The MiniMelf package offers a compact solution for space-constrained designs compared to larger axial leads. Consider the 500 mW power rating against expected thermal conditions. The low leakage current makes it suitable for high-impedance circuits where minimal current draw is critical.

Single Zener Diodes Part Context

This part belongs to the BZV55 series of low-power Zener diodes from Nexperia. The series provides a comprehensive range of voltages from 2.4 V to 75 V in small SMD packages. The 'B' suffix indicates the ±2% tolerance variant, while 'C' denotes ±5%. These diodes are engineered for general-purpose regulation and protection in consumer and industrial electronics.

Single Zener Diodes Replacement Considerations

Direct substitutes within the same family include BZV55-C39,115, which shares the same package and power rating but offers ±5% tolerance instead of ±2%. Other manufacturers may offer equivalent MiniMelf Zener diodes with matching 39 V ratings and 500 mW dissipation, provided pinout and thermal characteristics are verified.
