Overview
The Diotec Semiconductor KBPC804 is a single-phase bridge rectifier from the KBPC800 series, rated for an average forward current of 8 A and a peak repetitive reverse voltage of 400 V. It features a maximum forward voltage drop of 1.2 V at 4 A and a leakage current below 5 µA at 25°C. The device supports a peak forward surge current of up to 135 A (50 Hz) or 150 A (60 Hz). Operating within a junction temperature range of -50°C to +150°C, it utilizes a through-hole KBPC-4 package with solder pin termination.
Feature Summary
- Single-phase bridge configuration providing efficient AC-to-DC conversion
- High thermal stability supporting operation up to 150°C junction temperature
- Robust surge current handling capability for transient protection
Applications
- General-purpose power supply circuits
- Industrial control systems requiring standard reliability
- Commercial electronic equipment
Procurement Notes
Verify the specific suffix against official documentation to confirm exact electrical ratings, as the KBPC800 series spans multiple voltage grades. Ensure compliance with RoHS and ELV directives by checking the manufacturer's latest datasheet. Confirm that the procurement channel provides valid traceability for commercial-grade components intended for industrial applications.
Selection Notes
Select this component when an 8 A continuous current rating and 400 V blocking voltage are required in a compact through-hole format. Evaluate the thermal resistance parameters to ensure adequate heat dissipation for the target ambient conditions. Consider the 1500 ns typical reverse recovery time for compatibility with standard frequency applications.
Part Context
This part belongs to the KBPC800...KBPC810 family of single-phase bridge rectifiers manufactured by Diotec Semiconductor AG. The series covers various voltage ratings while maintaining consistent mechanical dimensions and current capabilities across the lineup.
Replacement Considerations
Compatible substitutes include other 8 A, 400 V single-phase bridge rectifiers in the KBPC-4 package. Verify equivalent forward voltage, leakage current, and thermal resistance specifications before substitution.
