BZM55B39-TR

Single Zener Diodes Overview

The BZM55B39-TR is a single Zener diode from Vishay's BZM55 series, housed in a MicroMELF (SOD-80) surface-mount package. It features a nominal Zener voltage of 39 V with a tolerance range of 38.2 V to 39.8 V. The device operates at a test current of 2.5 mA and dissipates up to 500 mW. Electrical characteristics include a maximum reverse leakage current of 100 nA at 2 V and a dynamic resistance of 90 Ω at the test current.

Single Zener Diodes Feature Summary

• Hermetically sealed glass encapsulation for high stability
• Very sharp reverse characteristic curve
• Low reverse leakage current levels
• Low noise performance

Single Zener Diodes Applications

• Voltage stabilization circuits
• Reference voltage generation
• Overvoltage protection

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging details. The -TR designation indicates a reel quantity of 2500 units on a 7-inch tape. Confirm that the component meets RoHS compliance requirements as defined by the manufacturer's material categorization standards before procurement.

Single Zener Diodes Selection Notes

Select this component when a precise 39 V reference is required in a compact SMD footprint. The BZM55B39 variant offers tighter voltage tolerance compared to the C-series. Ensure the application circuit can handle the specified 500 mW power dissipation and verify thermal management for the MicroMELF package.

Single Zener Diodes Part Context

This part belongs to the BZM55 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series provides electrical data identical to the BZT55 and TZM series but utilizes a space-saving MicroMELF package suitable for automated surface-mount assembly processes.

Single Zener Diodes Replacement Considerations

The datasheet states that electrical data is identical to the BZT55..series and TZM..series devices. These may serve as functional equivalents if package compatibility allows.
