KBPC802

Overview

The Diotec Semiconductor KBPC802 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 exhibits a maximum forward voltage drop of 1.2 V per diode at 4 A and maintains a leakage current below 5 µA at 25°C. Thermal performance includes a junction-to-case resistance under 3.3 K/W and a junction-to-ambient resistance below 10 K/W. Operating temperatures range from -50°C to +150°C, with surge current capabilities reaching 150 A.

Feature Summary

• Single-phase bridge configuration providing full-wave rectification in a compact through-hole package.
• High thermal stability allowing operation up to 150°C junction temperature.
• Low forward voltage drop characteristics to minimize conduction losses.
• Robust surge current handling capability for transient protection.

Applications

• General-purpose AC to DC power supply circuits.
• Industrial control systems requiring reliable rectification.
• Consumer electronics power adapters.

Procurement Notes

Verify the specific part number against official Diotec Semiconductor documentation to ensure compliance with electrical ratings. Confirm that the procurement channel provides valid traceability and authenticity guarantees. Check for any recent product changes or obsolescence notices on the manufacturer's website before finalizing orders.

Selection Notes

Select this component when an 8 A continuous current and 800 V blocking voltage are required in a standard bridge rectifier form factor. Ensure the application environment allows for adequate heat dissipation to maintain junction temperatures within the specified limits. Consider the physical dimensions and mounting torque requirements for PCB integration.

Part Context

The KBPC802 belongs to the KBPC800...KBPC810 series of single-phase bridge rectifiers from Diotec Semiconductor. This family shares identical mechanical dimensions and thermal characteristics, differing primarily in their peak repetitive reverse voltage ratings. The series is widely used in commercial and industrial applications where standard reliability levels are sufficient.

Replacement Considerations

Direct replacements must match the 8 A current rating, 800 V reverse voltage, and KBPC-4 package style. Verify that substitute components meet the same thermal resistance and forward voltage specifications to ensure circuit compatibility without redesign.
