KBPC800

Overview

The KBPC800 is a single-phase bridge rectifier manufactured by Diotec Semiconductor, designed for general-purpose power supply applications. It features an average forward current rating of 8 A at an ambient temperature of 50°C and supports peak repetitive reverse voltages up to 800 V. The device utilizes a through-hole mounting style within the KBPC-4 package. Key electrical characteristics include a maximum forward voltage of 1.2 V at 4 A, a leakage current below 5 µA, and a typical reverse recovery time of 1500 ns. Thermal resistance from junction to case is less than 3.3 K/W, while junction-to-ambient resistance is under 10 K/W.

Feature Summary

• Robust surge current handling capability with ratings of 135 A at 50 Hz and 150 A at 60 Hz.
• Wide operating temperature range spanning from -50°C to +150°C for junction and storage conditions.
• Low thermal resistance design facilitating efficient heat dissipation in compact assemblies.

Applications

• General-purpose AC/DC conversion circuits
• Power supply units requiring standard reliability
• Industrial control systems

Procurement Notes

Verify component authenticity against official Diotec Semiconductor documentation before integration. Confirm that the specific part number matches the required voltage and current specifications for the target application. Ensure compliance with RoHS and ELV directives as indicated in the datasheet. Validate thermal management requirements based on the specified junction-to-ambient resistance values.

Selection Notes

Select this component when an 8 A continuous current capacity and 800 V blocking voltage are required in a through-hole configuration. Consider the 1.2 V forward voltage drop for efficiency calculations. Evaluate the thermal environment to ensure the junction temperature remains within the +150°C limit under expected load conditions.

Part Context

This component belongs to the KBPC series of single-phase bridge rectifiers produced by Diotec Semiconductor. The series offers various voltage ratings alongside the 8 A current capability, providing standardized solutions for different power levels. The KBPC-4 package is widely used in industrial and commercial electronics for reliable rectification.

Replacement Considerations

Compatible substitutes must match the 8 A current rating, 800 V reverse voltage, and KBPC-4 package dimensions. Verify equivalent thermal resistance and forward voltage characteristics to maintain circuit performance without modification.
