MUR3020PT

Overview

The MUR3020PT is an ultrafast recovery rectifier diode manufactured by onsemi, designed for high-efficiency switching applications. It features a 30-ampere average forward current rating and supports repetitive peak reverse voltages of 200V, 400V, or 600V depending on the specific suffix variant. The device utilizes a TO-247AD package to facilitate effective thermal management. Key electrical characteristics include an ultrafast 35 nanosecond typical recovery time and a maximum junction temperature capability of 175°C. These specifications make it suitable for demanding power conversion environments requiring low leakage and high voltage resilience.

Feature Summary

• Ultrafast recovery performance with minimal reverse recovery charge for reduced switching losses
• High thermal stability supporting operation up to 175°C junction temperature
• Glass-passivated junction ensuring robust reliability under high-temperature conditions
• Epoxy casing meeting UL94 V-0 flammability ratings for safety compliance

Applications

• Switching power supply output rectification
• Free-wheeling diode implementation in inverter circuits
• High-frequency DC-DC converter stages

Procurement Notes

Verify the exact voltage suffix (e.g., 20, 40, 60) when ordering, as the base part number covers multiple voltage ratings. Confirm the TO-247AD package style matches your heatsinking requirements. Check for RoHS compliance status if environmental regulations apply to your assembly process. Ensure the supplier provides official datasheets corresponding to the specific voltage variant selected.

Selection Notes

Select this component for designs requiring fast switching speeds and high current handling in a single-ended configuration. Compare the specific reverse voltage rating needed against the available variants within the MUR3020 series. Consider the thermal resistance of the TO-247 package for your heat dissipation strategy. Evaluate the 35ns recovery time against your switching frequency to ensure efficiency gains over standard recovery diodes.

Part Context

This device belongs to the MUR series of ultrafast recovery rectifiers from onsemi, formerly Motorola. The series is engineered for high-performance power electronics where speed and efficiency are critical. The MUR3020PT specifically denotes the 200V variant in the TO-247 through-hole package. It complements other current ratings in the family, such as the MUR15 and MUR60 series, providing scalable solutions for various power levels.

Replacement Considerations

Direct substitutes include the MUR3020WT for surface-mount compatibility or other manufacturers' MUR3020 equivalents. Verify pinout compatibility and thermal characteristics before substitution. Ensure the replacement meets the same 175°C junction temperature rating and ultrafast recovery specifications.
