KBPC608

Overview

The KBPC608 is a single-phase silicon bridge rectifier manufactured by Diotec Semiconductor, rated for a repetitive peak reverse voltage of 800 V and an average forward current of 6 A. It utilizes the KBPC-4 through-hole package with solder pin termination. The device exhibits a maximum forward voltage drop of 1.2 V at 3 A and a typical reverse recovery time of 1500 ns. Operating junction temperatures range from -50°C to +150°C, supported by a thermal resistance of 3.3 K/W (junction-to-case). Peak forward surge current reaches 125 A under standard half-sine wave conditions.

Feature Summary

• High surge overload rating capable of handling significant transient currents
• Robust case dielectric strength suitable for demanding industrial environments
• Guaranteed high-temperature soldering capability up to 250°C

Applications

• Single-phase AC to DC power supply rectification
• Industrial equipment power conversion systems
• General-purpose bridge rectifier circuits in commercial electronics

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer's part number against official Diotec Semiconductor documentation. Confirm RoHS compliance status and specific packaging configurations directly with authorized distributors or the manufacturer prior to procurement. Ensure that the ordering suffix matches the required tape-and-reel or bulk packaging specifications for your assembly line.

Selection Notes

Select this component when a 6 A continuous current rating and 800 V blocking voltage are required in a compact through-hole configuration. Evaluate the 1.2 V forward voltage drop against system efficiency targets and ensure adequate heatsinking or airflow to maintain junction temperature within the specified -50°C to +150°C operational range during peak load conditions.

Part Context

This component belongs to the KBPC600 series, which encompasses bridge rectifiers ranging from 50 V to 1000 V reverse voltage ratings. All members of this family share identical physical dimensions and thermal characteristics, differing only in their maximum repetitive peak reverse voltage capabilities. This allows for standardized mechanical design across various voltage requirements.

Replacement Considerations

Direct replacements must match the 6 A current rating, 800 V reverse voltage, and KBPC-4 package outline. Verify that alternative manufacturers provide equivalent forward voltage drops and thermal resistance values to ensure compatibility with existing thermal management designs.
