KBPC808

Overview

The Diotec Semiconductor KBPC808 is a single-phase bridge rectifier designed for general-purpose applications. It features an average forward current rating of 8 A at an ambient temperature of 50°C and supports a peak repetitive reverse voltage of 800 V. The device utilizes a standard silicon construction housed in a KBPC-4 package with screw mounting terminals. Key electrical characteristics include a maximum forward voltage of 1.2 V per diode at 4 A, a leakage current below 5 µA at rated voltage, and a typical reverse recovery time of 1500 ns. Thermal resistance from junction to case is less than 3.3 K/W, while the junction-to-ambient resistance is under 10 K/W.

Feature Summary

• Robust surge current capability with a non-repetitive peak forward surge current of 150 A at 60 Hz.
• Wide operating temperature range supporting junction and storage temperatures from -50°C to +150°C.
• Low thermal resistance design facilitating efficient heat dissipation from the junction to the case.

Applications

• General-purpose AC to DC power supply circuits
• Industrial control systems requiring reliable rectification
• Battery charging equipment

Procurement Notes

Verify the specific part number suffix against official Diotec documentation to confirm exact mechanical or electrical variations. Ensure that the procurement specifications align with the required voltage and current ratings for the target application. Confirm compliance with relevant environmental directives such as RoHS and ELV before finalizing orders.

Selection Notes

Select the KBPC808 when an 8 A continuous current and 800 V blocking voltage are required in a screw-mountable bridge configuration. Evaluate the thermal management requirements based on the specified junction-to-case thermal resistance. Consider the 1500 ns reverse recovery time for frequency limitations in the intended circuit design.

Part Context

The KBPC808 belongs to the KBPC series of single-phase bridge rectifiers manufactured by Diotec Semiconductor. This series encompasses various voltage ratings ranging from 50 V to 1000 V, all sharing the same 8 A current rating and standardized KBPC-4 package dimensions. The series is widely used in commercial and industrial electronics where robust performance and standard mounting are prioritized.

Replacement Considerations

Cross-reference with other manufacturers offering 8 A, 800 V bridge rectifiers in the KBPC-4 package. Verify pinout compatibility and ensure that thermal resistance and surge current ratings meet or exceed the original specifications.
