• Soft recovery characteristics to reduce electromagnetic interference and ringing
• High-temperature glass passivated junction for enhanced reliability
• Common cathode dual configuration suitable for bridge rectifier circuits

Applications

• Negative switching power supplies
• Inverter circuits
• Freewheeling diode implementations
• Single-phase full-wave bridge rectifiers when paired with complementary devices

Procurement Notes

Verify the specific revision level of the datasheet, as ON Semiconductor has issued multiple updates (Rev. 5 through Rev. 15) for this part number over time. Confirm that the ordering suffix matches the required tape and reel quantity and packaging specifications. Ensure compliance with RoHS and lead-free requirements if applicable to the assembly process. Cross-reference the manufacturer's official documentation for any changes in mechanical dimensions or marking codes.

Selection Notes

Select this component for designs requiring fast recovery times below 40 nanoseconds and moderate current handling up to 6 Amperes. The common cathode arrangement simplifies layout compared to discrete single diodes. Consider the thermal performance of the D2PAK package and ensure adequate heatsinking or PCB copper area to manage power dissipation at elevated ambient temperatures. Verify compatibility with the target switching frequency to leverage the soft recovery benefits.

Part Context

This device belongs to the MUR series of SwitchMode Power Rectifiers from ON Semiconductor. It is functionally related to other ultrafast diodes such as the MURB1660CTT4G and MURD320T4G, though these differ in voltage ratings and current capacities. The MURD620CTT4G specifically targets applications needing a balance between speed and current rating in compact surface-mount form factors.

Replacement Considerations

Public confirmed substitute part numbers include MURD620CTR and MURD620CTRG. These variants share identical electrical specifications and pinout configurations. Verify that the replacement variant meets the same environmental and packaging requirements as the original design specification.
