Overview
The GeneSiC Semiconductor KBPC5004T is a single-phase silicon bridge rectifier rated for a repetitive peak reverse voltage of 400 V and a maximum average forward rectified current of 50 A. It features a peak forward surge current capability of 400 A and a typical thermal resistance per leg of 2.5 °C/W. The device operates within a junction temperature range of -55 °C to +150 °C, with a maximum instantaneous forward voltage of 1.1 V at Tc = 25 °C and IF = 25.0 A.
Feature Summary
- High efficiency rectification using silicon junction technology
- Robust metal case encapsulation designed for mechanical durability
- Non-ESD sensitive construction suitable for standard handling
Applications
- General purpose AC to DC power conversion circuits
- Industrial equipment requiring high surge current tolerance
- Power supplies utilizing resistive or inductive loads
Procurement Notes
Verify the specific datasheet revision date against the manufacturer's official documentation before procurement. Confirm that the GBPC or KBPC package dimensions match the target PCB footprint requirements. Ensure thermal management strategies account for the specified thermal resistance values under actual operating conditions rather than idealized test parameters.
Selection Notes
Select this component when a 400 V blocking voltage and 50 A continuous current rating are required. Consider the 2.5 °C/W thermal resistance for heat sink calculations. Verify compatibility with the mounting hole configuration for #10 screws. Derate the forward current by 20% if the application involves capacitive loads to ensure reliable operation within the specified temperature limits.
Part Context
This part belongs to the KBPC-T series of single-phase bridge rectifiers manufactured by GeneSiC Semiconductor. The series encompasses various voltage ratings from 50 V to 400 V, sharing common physical dimensions and thermal characteristics. The 'T' suffix indicates the specific KBPC-T package variant used for this model.
Replacement Considerations
Cross-reference with other manufacturers offering KBPC package bridge rectifiers rated at 50 A and 400 V. Ensure equivalent thermal resistance and forward voltage specifications. Verify that the replacement part supports the same mounting hole pattern and polarity marking conventions.
