MURB1620CT

Overview

The MURB1620CT is a dual common cathode ultrafast recovery rectifier manufactured by Vishay. It features two independent legs, each rated for an average forward current of 8 A and a peak repetitive reverse voltage of 200 V. The device utilizes FRED Pt technology to achieve an ultrafast reverse recovery time of 25 ns typical value. Electrical specifications include a maximum forward voltage drop of 0.975 V at 8 A and a low leakage current of 5 µA at rated voltage. The component operates within a junction temperature range of -65 °C to 175 °C and is housed in a D2PAK surface-mount package.

Feature Summary

• Ultrafast recovery characteristics enabled by platinum-doped lifetime control
• Low forward voltage drop optimized for high efficiency
• Designed for industrial level reliability and ruggedness
• Planar structure ensures stable performance under thermal stress

Applications

• Output rectification stage of switch-mode power supplies (SMPS)
• Uninterruptible power supply (UPS) systems
• DC-to-DC converters
• Freewheeling diodes in low voltage inverters
• Chopper motor drives

Procurement Notes

Verify the specific ordering suffix to confirm the required packaging format, such as tube or tape and reel orientation. Confirm lead-free status if RoHS compliance is mandatory for the assembly process. Ensure the selected variant matches the intended mounting style, distinguishing between the standard D2PAK case and the TO-262 option. Cross-reference the datasheet revision date with manufacturing lot codes to ensure consistency with current production standards.

Selection Notes

Select this component when applications require fast switching speeds to minimize reverse recovery losses and electromagnetic interference. The dual common cathode configuration allows for full-wave bridge rectification using only two devices. Consider the thermal resistance values when designing heatsinking solutions for high ambient temperatures. Verify that the peak surge current rating exceeds the expected inrush currents in the target circuit design.
