MURB1620CTT4G

Overview

The MURB1620CTT4G is an ultrafast recovery rectifier manufactured by onsemi, housed in a D2PAK-3 (TO-263-3) surface-mount package. It features a dual common cathode configuration with a maximum repetitive reverse voltage of 200 V and an average forward current rating of 16 A per diode. The device exhibits a typical forward voltage of 975 mV at rated current and a maximum reverse leakage current of 5 uA. Key electrical characteristics include a peak non-repetitive surge current capability of 100 A and a fast reverse recovery time of 35 ns. The component operates within a junction temperature range of -65 °C to +175 °C.

Feature Summary

• Ultrafast recovery performance with 35 ns reverse recovery time for efficient switching applications
• Dual common cathode configuration integrating two independent rectifiers in a single package
• High thermal stability supporting operation up to +175 °C junction temperature
• Robust surge handling capability with 100 A peak non-repetitive forward current rating

Applications

• High-frequency DC/DC converter output rectification
• Free-wheeling diodes in synchronous rectifier circuits
• Power factor correction (PFC) stages
• Automotive electronics power management systems

Procurement Notes

Verify the specific suffix T4G confirms lead-free and RoHS compliance status against the latest manufacturer documentation. Confirm the D2PAK-3 package dimensions match your PCB footprint requirements. Ensure the dual common cathode topology aligns with your circuit design rather than common anode variants. Check for any recent product change notices that may affect pinout or material composition.

Selection Notes

Select this component when high-speed switching efficiency is required alongside moderate current handling capabilities. The 200 V rating suits low-voltage DC bus applications. Consider the thermal resistance of the D2PAK package for heat dissipation needs. Compare the 35 ns recovery time against slower alternatives if minimizing switching losses is critical. Verify compatibility with your operating frequency constraints.

Part Context

This part belongs to the MURB1620CT series of silicon rectifiers designed for general-purpose ultrafast recovery applications. It shares the same electrical specifications as the through-hole MURB1620CTRG variant but utilizes a surface-mount package for automated assembly. The series targets cost-sensitive designs requiring reliable performance in compact power supplies.

Replacement Considerations

MURB1620CTRT4G offers identical electrical parameters but uses a common anode configuration instead of common cathode. MURB1660CTT4G provides similar packaging but higher voltage ratings. Verify pinout compatibility before substituting common anode parts into common cathode designs.
