Overview
The Diotec Semiconductor KBPC604 is a single-phase diode bridge rectifier designed for general-purpose power conversion applications. It features an average forward current rating of 6 A and a maximum repetitive peak reverse voltage of 400 V. The device exhibits a typical forward voltage drop of less than 1.2 V at 3 A and maintains a low leakage current below 5 µA at 25°C. Key electrical characteristics include a peak forward surge current capability of 125 A at 60 Hz and a typical reverse recovery time of 1500 ns. Thermal performance is defined by a junction-to-case thermal resistance of 3.3 K/W, supporting operation within a junction temperature range of -50°C to +150°C.
Feature Summary
- Robust surge current handling capability suitable for inductive load switching
- Low forward voltage drop to minimize conduction losses
- High thermal stability with extended operating temperature range
Applications
- General-purpose AC-DC power supply rectification
- Battery charging circuits
- Industrial control systems
Procurement Notes
Verify the specific part number suffix against official Diotec documentation to confirm exact packaging configuration and compliance markings. Confirm that the component meets RoHS and ELV directives as stated in the datasheet. Ensure the ordering details match the required commercial grade specifications before finalizing procurement.
Selection Notes
Select this component when a 6 A continuous current rating and 400 V blocking voltage are required for standard commercial applications. Evaluate the thermal resistance parameters to ensure adequate heat dissipation for the intended ambient conditions. Consider the 1500 ns reverse recovery time for compatibility with the target switching frequency.
Part Context
The KBPC604 belongs to the KBPC600...KBPC610 series of single-phase bridge rectifiers from Diotec Semiconductor. This family provides standardized ratings across varying voltage classes while maintaining consistent current and package characteristics. The series is engineered for reliable performance in standard industrial and commercial environments.
Replacement Considerations
Consult official manufacturer substitution lists for verified equivalents. Generic replacements must match the 6 A current, 400 V voltage, and KBPC-4 package dimensions.
