BYW82-TR

Overview

The BYW82-TR is a high-speed switching diode manufactured by Vishay General Semiconductor. It features a fast recovery time and low forward voltage drop, making it suitable for efficient power conversion applications. The component is housed in a compact SOD-123 surface-mount package, designed for automated assembly processes. Key electrical characteristics include a maximum repetitive peak reverse voltage of 100 V and an average forward rectified current rating of 1 A. The device exhibits a typical reverse recovery time of 5 ns, ensuring minimal switching losses in high-frequency circuits.

Feature Summary

• Fast recovery characteristics for high-frequency switching operations
• Low forward voltage drop to enhance energy efficiency
• Compact surface-mount packaging for space-constrained designs

Applications

• High-frequency DC-DC converters
• Free-wheeling diodes in synchronous rectification circuits
• Snubber circuits in switch-mode power supplies

Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging when ordering. Confirm that the voltage and current ratings align with your circuit's peak requirements. Ensure compatibility with standard SMD reflow soldering profiles. Check for RoHS compliance status if required by your manufacturing standards. Validate the manufacturer's datasheet for any recent revisions affecting mechanical dimensions or electrical limits.

Selection Notes

Choose this component when fast recovery speed is critical to minimize switching losses. The SOD-123 package offers a balance between thermal performance and board space savings. Consider the 100 V reverse voltage rating against potential voltage spikes in your application. Evaluate the thermal resistance characteristics if operating near maximum current limits. Compare with similar Schottky diodes if lower forward voltage is prioritized over reverse recovery speed.

Part Context

This diode belongs to Vishay's family of fast recovery rectifiers designed for modern power electronics. It complements other surface-mount devices in their portfolio aimed at improving converter efficiency. The technology leverages advanced silicon planar passivation for reliability. Similar parts in the series may offer different voltage ratings or current capacities while maintaining comparable recovery times.

Replacement Considerations

Direct substitutes include the BYV27E-TR from the same manufacturer, which shares similar electrical characteristics. Other compatible alternatives may include components from ON Semiconductor or Diodes Inc. with matching SOD-123 packages and equivalent voltage/current ratings. Verify pinout compatibility and thermal performance before substitution.
