Diode Arrays Procurement Notes

Verify the specific ordering suffix 'T4' indicates tape and reel packaging containing 800 units per reel, distinct from the rail-packaged 'D' or 'G' variants. Confirm that the component meets MSL1 moisture sensitivity requirements and Pb-Free specifications if required by the assembly process. Ensure terminal connections are properly managed for parallel operation as specified in the mechanical characteristics.

Diode Arrays Selection Notes

Select this component when designing circuits requiring a 200 V reverse voltage rating and high-frequency switching capabilities up to 5.0 MHz. The D2PAK package is suitable for surface-mount applications needing robust thermal dissipation with a junction-to-case thermal resistance of 2.0 °C/W. Consider the dual common cathode configuration and the necessity of connecting terminals 1 and 3 for full current capacity utilization.

Diode Arrays Part Context

This part belongs to the MBRB20200 series of SwitchMODE power rectifiers from onsemi. It shares the core electrical specifications with the MBRB20200CT and MBRB20200CTG but differs in shipping packaging. The series is designed for efficiency in DC-DC converters and general power rectification where low forward voltage drop is critical for minimizing power loss.

Diode Arrays Replacement Considerations

The MBRB20200CTT4G is a verified Pb-free alternative within the same series offering identical electrical characteristics and pinout compatibility. Verify package dimensions and thermal resistance values match the existing design constraints before substitution.
