MBR30H100CT-M3/4W

Diode Arrays Overview

The MBR30H100CT-M3/4W is a high-voltage Schottky rectifier manufactured by Vishay General Semiconductor. It utilizes High Barrier Technology to deliver superior thermal performance and reliability compared to standard Schottky diodes. The device features a dual common-cathode configuration within a single TO-220AB package, making it suitable for applications requiring efficient power conversion. Key electrical characteristics include a repetitive peak reverse voltage of 100 V and an average forward current rating of 15 A per element. The component is designed for high-frequency operation with low forward voltage drop and minimal leakage current.

Diode Arrays Feature Summary

• High Barrier Technology ensures improved high-temperature performance and reduced leakage current
• Dual common-cathode configuration allows for compact circuit design in bridge or full-wave applications
• Guardring structure provides enhanced overvoltage protection capabilities
• Low forward voltage drop contributes to lower power losses and higher system efficiency

Diode Arrays Applications

• High frequency rectification in switching mode power supplies
• Freewheeling diodes in DC-to-DC converters
• Polarity protection circuits in electronic systems

Diode Arrays Procurement Notes

Verify the specific suffix /4W against official Vishay documentation to confirm package variant details, as standard listings often default to /45 or similar. Confirm RoHS compliance status via the manufacturer's latest datasheet revision. Check for end-of-life notifications or discontinuation notices prior to finalizing procurement plans. Ensure the ordering part number matches the exact pinout and mechanical dimensions required for the target PCB footprint.

Diode Arrays Selection Notes

Select this component when high reverse voltage blocking capability combined with fast switching speeds is required. The dual common-cathode arrangement simplifies layout for full-bridge or center-tapped rectifier topologies. Consider the thermal resistance of the TO-220AB package for heat dissipation requirements. Evaluate the forward voltage characteristics at expected operating temperatures to ensure efficiency targets are met in the power conversion stage.

Diode Arrays Part Context

This part belongs to Vishay's MBR30H series of High Barrier Schottky Rectifiers. These devices are engineered to overcome the traditional trade-off between reverse leakage current and forward voltage drop found in conventional silicon Schottky diodes. The series is widely used in industrial and consumer power supplies where reliability under high thermal stress is critical. The M3 designation typically indicates lead-free and halogen-free construction compliant with environmental directives.

Diode Arrays Replacement Considerations

Direct replacements may include the MBR30H100CT-G1 from Diodes Incorporated, which shares similar electrical ratings and package type. Verify that any substitute maintains the same dual common-cathode configuration and thermal performance characteristics. Cross-reference mechanical dimensions to ensure compatibility with existing mounting hardware and PCB layouts.
