Overview
The LMB204S-TP is a single-phase bridge rectifier from the LMB203S series by Micro Commercial Components. It features a 2.0A average rectified forward current and a 400V maximum repetitive reverse voltage rating. The device utilizes glass passivated chip junctions for enhanced reliability and is housed in a surface mount package with epoxy meeting UL 94 V-0 flammability ratings. Key electrical characteristics include a typical forward voltage of 0.95V at 1.0A and a non-repetitive peak surge current of 110A. Thermal resistance from junction to case is specified at 8°C/W.
Feature Summary
- Glass passivated chip junctions provide robust protection against voltage transients.
- Surface mount packaging facilitates automated assembly processes.
- Epoxy material complies with UL 94 V-0 flammability standards.
- Halogen-free construction supports environmentally conscious manufacturing.
Applications
- General purpose AC to DC power supply conversion
- Adapter circuits for consumer electronics
- Low voltage DC power distribution systems
Procurement Notes
Verify authenticity through authorized MCC distributors or direct channels due to counterfeiting risks. Confirm RoHS compliance status via official documentation. Ensure storage conditions align with moisture sensitivity level requirements. Check for obsolescence notices as the component may be subject to design phase-out recommendations.
Selection Notes
Select this component for applications requiring compact surface mount rectification with moderate current handling capabilities. Evaluate thermal management strategies based on the specified junction-to-case resistance. Consider the 400V reverse voltage rating relative to peak line voltages in the target circuit design to ensure adequate safety margins during operation.
Part Context
This part belongs to the LMB203S family, which includes variants rated from 200V to 1000V. All members share identical physical dimensions and thermal characteristics while differing only in their peak reverse voltage specifications. The series is designed for general-purpose rectification tasks where space constraints necessitate surface mount technology solutions.
Replacement Considerations
Direct substitutes within the same series include LMB203S, LMB205S, LMB206S, and LMB207S. These alternatives offer different voltage ratings but maintain identical pinouts and mechanical profiles. Verify that the replacement's voltage rating exceeds the application's maximum reverse voltage requirements before implementation.
