Overview
The KBJA402-BP is a single-phase bridge rectifier from the KBJA series manufactured by Micro Commercial Components. It features glass passivated chip junctions and an average forward current rating of 4 A at a case temperature of 120°C. The device supports a peak repetitive reverse voltage (VRRM) of 200 V, with corresponding working peak reverse voltage and DC blocking voltage ratings of 140 V and 280 V respectively. It withstands a non-repetitive peak surge current of 135 A under an 8.3 ms half-sine wave condition. The component operates within a junction temperature range of -55°C to 150°C.
Feature Summary
- Glass passivated chip junctions provide reliable operation and enhanced stability against environmental fluctuations.
- High surge forward current capability ensures robust performance during transient electrical events.
- Epoxy casing meets UL 94 V-0 flammability ratings for improved safety compliance.
Applications
- AC-to-DC power supply circuits
- Battery charging systems
- General-purpose rectification in electronic equipment
Procurement Notes
Verify authenticity through authorized MCC distributors or direct procurement channels due to industry counterfeiting risks. 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 component when a 4 A continuous current rating and 200 V reverse voltage blocking capability are required. Consider the thermal resistance characteristics and derating curves if operating near maximum case temperatures. Verify package dimensions fit the target PCB layout constraints.
Part Context
This part belongs to the KBJA series of bridge rectifiers, which share common mechanical and electrical characteristics across varying voltage ratings. The series utilizes a JB package style designed for through-hole mounting. Other variants in the family include different voltage ratings such as KBJA401 and KBJA404.
Replacement Considerations
Direct substitutes must match the 4 A current rating, 200 V reverse voltage, and JB package footprint. Verify that alternative components offer comparable surge current capabilities and thermal resistance values to ensure circuit reliability without redesign.
