Overview
The KBPC10/15/2504WP is a single-phase silicon bridge rectifier from Diotec Semiconductor. It provides a repetitive peak reverse voltage (VRRM) of 400 V and a maximum alternating input voltage (VVRMS) of 280 V. The device supports average forward rectified output currents (IFAV) of 10 A, 15 A, or 25 A depending on the specific sub-model variant, with a peak forward surge current (IFSM) of 270 A at 50 Hz. Operating temperatures range up to a maximum junction temperature (Tjmax) of 150°C. The component utilizes wire terminals for connection and features an isolated aluminum baseplate within a plastic case.
Feature Summary
- Four diodes integrated in a bridge configuration
- Plastic case equipped with an isolated aluminum baseplate
- UL recognized under File E175067
- Compliant with RoHS directives
Applications
- 50/60 Hz mains rectification
- Commercial power supplies
- Industrial grade equipment
Procurement Notes
Verify the exact sub-model suffix corresponding to the required current rating (KBPC10, KBPC15, or KBPC25) when ordering. Confirm that the WP designation matches the requirement for wire terminals rather than fast-on connectors. Ensure compliance with standard commercial or industrial reliability grades unless automotive qualification is explicitly needed.
Selection Notes
Select the appropriate current rating based on the thermal management strategy; higher currents require larger cooling fins or forced air convection. Verify that the 400 V reverse voltage rating exceeds the peak line voltage plus any transient spikes. Check if wire termination is suitable for the assembly process, as soldering conditions must adhere to specified limits.
Part Context
This component belongs to the KBPC series of single-phase bridge rectifiers manufactured by Diotec Semiconductor. The series offers various voltage ratings from 100 V to 1800 V and current ratings up to 25 A. The KBPC10/15/2504WP specifically addresses applications requiring 400 V blocking capability with wire lead connections.
Replacement Considerations
Check for generic KBPCxxxxWP equivalents from other manufacturers offering identical 400 V and 10-25 A ratings. Verify pinout compatibility and terminal type before substitution.
