RBV804

Bridge Rectifier Overview

The RBV804 is a silicon bridge rectifier from the RBV800 series manufactured by EIC Semiconductor Inc. It provides a maximum recurrent peak reverse voltage of 400 V and a maximum average forward current of 8.0 A at a case temperature of 55°C. The device features a peak forward surge current capability of 300 A for single half-sine waves. Electrical characteristics include a maximum forward voltage drop of 1.0 V at 4.0 A, with typical thermal resistance from junction to case rated at 2.5 °C/W. The component supports an operating junction temperature range from -40°C to +150°C.

Bridge Rectifier Feature Summary

• High current and high surge current capabilities designed for robust power applications
• Low reverse leakage current and low forward voltage drop for improved efficiency
• Rated isolation voltage of 2000 V AC ensuring reliable electrical safety
• Molded plastic construction with UL94V-0 flame retardant epoxy

Bridge Rectifier Applications

• Printed circuit board mounting for general-purpose rectification
• Single-phase half-wave rectification in resistive or inductive loads
• Power supply units requiring high reliability and heat dissipation

Bridge Rectifier Procurement Notes

Verify the manufacturer designation as EIC Semiconductor Inc. against official documentation. Confirm the specific part number RBV804 matches the 400 V rating within the RBV800 series. Ensure compliance with RoHS standards and check terminal solderability specifications per MIL-STD-202 Method 208 during quality assurance.

Bridge Rectifier Selection Notes

Select this component when a 400 V blocking voltage and 8.0 A continuous current are required. Consider the 300 A surge rating for transient protection needs. Evaluate the thermal resistance of 2.5 °C/W against the expected heatsink configuration on a 3.2-inch aluminum plate. Verify that the operating temperature range meets the environmental requirements of the target application.

Bridge Rectifier Part Context

The RBV804 belongs to the RBV800-RBV810 family of silicon bridge rectifiers. This series offers varying reverse voltage ratings from 50 V to 1000 V while maintaining a consistent 8.0 A forward current capacity. The components share identical mechanical dimensions and thermal characteristics, differing primarily in their voltage handling capabilities.

Bridge Rectifier Replacement Considerations

Cross-reference other RBV800 series variants for different voltage ratings. Check equivalent bridge rectifiers from other manufacturers offering 400 V and 8.0 A specifications. Verify pinout compatibility and package dimensions before substitution.
