MUR1620CT

Overview

The MUR1620CT is a silicon ultra-fast recovery rectifier diode manufactured by Taiwan Semiconductor Corporation. It features a common cathode configuration with two internal elements housed in a TO-220AB package. The device supports a maximum average forward current of 8 amperes per leg and a peak repetitive reverse voltage of 200 volts. Key electrical characteristics include a maximum non-repetitive peak forward surge current of 100 amperes, a typical reverse recovery time of 35 nanoseconds, and a maximum junction temperature rating of 175 degrees Celsius.

Feature Summary

• Ultra-fast recovery performance with soft recovery characteristics to minimize switching noise
• High thermal stability enabled by glass passivated junctions
• Common cathode dual configuration for efficient bridge applications

Applications

• Negative switching power supplies
• Inverter circuits
• Freewheeling diode implementations
• Single-phase full-wave bridge configurations

Procurement Notes

Verify the manufacturer designation on the component marking to confirm Taiwan Semiconductor origin, as this part number is widely produced by multiple vendors including ON Semiconductor. Ensure the package style matches the required TO-220AB footprint. Check datasheets for specific reverse recovery time variations between manufacturers. Confirm compliance requirements such as RoHS status if applicable to the assembly process.

Selection Notes

Select this component when designing circuits requiring fast switching speeds and low reverse recovery charge. The common cathode arrangement simplifies layout compared to discrete pairs. Consider the 8A per leg rating against total load requirements. Evaluate thermal management needs given the high surge current capability. Verify that the 200V blocking voltage provides sufficient margin for the specific application voltage spikes.

Part Context

This device belongs to the MUR series of ultra-fast recovery rectifiers designed for high-frequency switching applications. It serves as a complement to common anode variants like the MUR1620AR. The technology utilizes advanced silicon planar epitaxial structures to achieve superior speed and reliability compared to standard recovery diodes.

Replacement Considerations

The MURB1620CT is a surface mount equivalent in the D2PAK package. Cross-reference datasheets from other manufacturers such as Micro Commercial Components or Yangjie Technology for pin-compatible alternatives. Verify that substitute parts meet the same 35ns reverse recovery time specification.
