Overview
The KBJA410-BP is a single-phase bridge rectifier from the KBJA series manufactured by Micro Commercial Components. It features glass passivated chip junctions and an epoxy body rated UL 94 V-0. The device supports a maximum repetitive peak reverse voltage of 1000V with an average rectified forward current of 4A at a case temperature of 120°C. Non-repetitive peak surge current reaches 270A for a 1ms square wave or 135A for an 8.3ms half-sine wave. Electrical characteristics include a maximum forward voltage of 1.0V at 2A, a maximum reverse leakage current of 100µA at 125°C, and a junction capacitance of 40pF at 4V reverse bias. Operating temperatures range from -55°C to 150°C.
Feature Summary
- Glass passivated chip junctions provide reliable performance under varying thermal conditions.
- Epoxy casing meets UL 94 V-0 flammability ratings for enhanced safety.
- High surge forward current capability ensures robustness against transient electrical loads.
Applications
- General-purpose AC to DC power supply circuits
- Battery charging systems requiring high reverse voltage tolerance
- Industrial control equipment operating in extreme temperature environments
Procurement Notes
Verify authenticity through authorized MCC distributors to avoid counterfeit components. Confirm RoHS compliance via the "BP" suffix designation. Ensure storage conditions align with manufacturer guidelines to maintain component integrity prior to assembly.
Selection Notes
Select this model for applications requiring 1000V blocking capability and 4A continuous current. Evaluate thermal resistance requirements based on heatsink usage versus ambient mounting. Consider derating curves for operation above 25°C case temperature to ensure reliability within specified limits.
Part Context
This component belongs to the KBJA series of bridge rectifiers designed for through-hole mounting. It shares common mechanical dimensions and electrical characteristics with other variants in the family, differentiated primarily by their peak repetitive reverse voltage ratings ranging from 50V to 1000V.
Replacement Considerations
Compatible substitutes include KBJA406-BP (600V) if voltage margins allow, or KBJ4010-BP from alternative manufacturers offering similar 4A/1000V specifications. Verify pinout compatibility and thermal resistance values before implementation.
FAQ
What is the maximum non-repetitive peak surge current for the KBJA410-BP?
The device supports a non-repetitive peak surge current of 135A for an 8.3ms half-sine wave and 270A for a 1ms square wave.
How does the average forward current change with case temperature?
The rated average rectified forward current of 4A is specified at a case temperature of 120°C. Derating curves indicate reduced current capacity as case temperature increases beyond standard operating ranges.
What is the typical junction capacitance value?
The junction capacitance is typically 40pF when measured at 4V reverse bias and 1MHz frequency with a junction temperature of 25°C.
