Overview
The KBPC5010FP is a single-phase silicon bridge rectifier from Diotec Semiconductor, rated for a repetitive peak reverse voltage of 1000 V and a maximum average forward current of 50 A. It utilizes fast-on terminals (6.3 mm) for mounting and features an isolated aluminum baseplate within a plastic case. The device supports forced cooling to maintain its 50 A rating at a case temperature of 50°C, with a derated capacity of 46 A under capacitive loads. Peak forward surge current reaches 400 A at 50 Hz and 450 A at 60 Hz. Typical thermal resistance from junction to case is 1.2 K/W per device.
Feature Summary
- Four diodes integrated in a bridge configuration
- Plastic case construction with an isolated aluminum baseplate
- Fast-on terminal design compatible with 6.3 mm connectors
- UL recognized component under file E175067
Applications
- 50/60 Hz mains rectification
- Commercial power supplies
- Industrial grade equipment
Procurement Notes
Verify the specific suffix FP to confirm the presence of fast-on terminals rather than wire leads. Confirm RoHS compliance status as exemption 7a-I applies. Check for automotive-grade variants if AEC-Q101 qualification is required for the target application environment.
Selection Notes
Select this component when a 1000 V blocking capability and 50 A continuous current are necessary. Ensure the PCB or heatsink design accommodates the isolated metal baseplate for proper thermal management. Verify that the 6.3 mm fast-on connector style matches the assembly requirements.
Part Context
This part belongs to the KBPC series of single-phase bridge rectifiers manufactured by Diotec Semiconductor. The series includes various voltage ratings from 100 V to 1200 V and current ratings up to 50 A. The KBPC5010FP specifically addresses high-current applications requiring robust isolation and standardized mounting interfaces.
Replacement Considerations
Consult official Diotec documentation for confirmed substitute part numbers. Generic equivalents may differ in terminal style, thermal resistance, or isolation characteristics.
