Overview
The MDD KBPC5010 is a single-phase silicon bridge rectifier in the KBPC series, rated for a maximum repetitive peak reverse voltage of 1000V and an average forward output rectified current of 50A at a case temperature of 55°C. It features a molded plastic body with solder-plated terminals and polarity marking. The device supports a peak forward surge current of 400A under JEDEC conditions and operates within a junction temperature range of -65°C to +150°C. Key electrical parameters include a maximum instantaneous forward voltage drop of 1.1V at 25A and a thermal resistance of 2.0°C/W.
Feature Summary
- High forward surge current capability
- Low reverse leakage current
- High temperature soldering guaranteed up to 260°C
- Underwriters Laboratory flammability classification 94V-0
Applications
- Printed circuit board mounting
- General purpose rectification in power supplies
- Industrial equipment requiring high current handling
Procurement Notes
Verify that the ordered component matches the original MDD part number KBPC5010. Confirm the package configuration is bulk packaging containing 50 pieces per box. Ensure compliance with RoHS and RoHS III standards as specified in the datasheet. Check for the specific part code KBPC50100L500A if sourcing from distributors using cross-reference codes. Validate terminal solderability per MIL-STD-750 Method 2026.
Selection Notes
Select this component when a 1000V reverse voltage rating and 50A continuous forward current are required. Consider the 2.0°C/W thermal resistance for heat sink design calculations. Ensure the application allows for through-hole mounting on printed circuit boards. Verify that the operating environment stays within the -65°C to +150°C junction temperature range. Account for current derating by 20% if capacitive loads are present.
Part Context
The KBPC5010 belongs to the KBPC series of thru-hole silicon bridge rectifiers manufactured by MDD. This series includes variants with different voltage ratings such as KBPC5005 and KBPC5008. The KBPC5010 specifically denotes the 1000V reverse voltage variant within the 50A current class family.
Replacement Considerations
Cross-reference part numbers include KBPC50100L500A. Verify pinout compatibility and thermal characteristics before substitution.
