MURB1620CTRT4

Overview

The MURB1620CTRT4G is an ultrafast recovery rectifier from onsemi, packaged in a D2PAK-3 (TO-263-3) surface-mount housing. It features a dual common cathode configuration with a maximum repetitive peak reverse voltage of 200 V and an average forward current rating of 16 A per package. The device exhibits a typical forward voltage drop of 975 mV and a fast reverse recovery time of 35 ns. It supports a maximum non-repetitive peak surge current of 100 A and operates within a junction temperature range of -65 °C to +175 °C.

Feature Summary

• Ultrafast 35 nanosecond reverse recovery time for high-frequency switching applications
• Soft recovery characteristics to minimize electromagnetic interference during switching transitions
• High-temperature glass passivated junction ensuring reliability under thermal stress
• Dual common cathode configuration allowing integration into full-wave bridge 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 complete part number suffix against official documentation, as variations such as 'T4G' or 'RG' may indicate specific packaging formats like cut tape or reel quantities. Confirm RoHS compliance status and lead times directly with authorized distributors. Ensure the ordering code matches the required pinout and polarity markings specified in the manufacturer's mechanical data sheet.

Selection Notes

Select this component for designs requiring low reverse recovery charge and high thermal stability. The D2PAK package provides robust heat dissipation capabilities suitable for moderate power levels. Consider the 200 V blocking voltage and 16 A current capacity relative to circuit load requirements. Evaluate the soft recovery feature if noise reduction is critical in sensitive analog sections of the power supply design.

Part Context

This device belongs to the MURB series of ultrafast rectifiers manufactured by onsemi. It serves as a complement to the MUR1620CT common cathode device, offering a common anode alternative for bridge configurations. The series is designed for general-purpose high-efficiency rectification in modern switching mode power supplies.

Replacement Considerations

The MUR1620CTR is documented as a complementary device within the same family. Verify pinout compatibility and electrical parameter equivalence before substitution. Check for any differences in packaging dimensions or marking codes that might affect assembly processes.
