Diode Arrays Procurement Notes

Verify the specific ordering suffix 'P' against official Littelfuse documentation to confirm tube packaging specifications. Ensure that the electrical ratings align with your circuit's thermal management requirements, particularly regarding the 10A per leg limit at 105°C case temperature. Confirm RoHS compliance status through the manufacturer's latest datasheet revision before finalizing procurement orders.

Diode Arrays Selection Notes

Select this component when designing circuits requiring high-frequency operation with low leakage currents. The ITO-220AB package facilitates efficient heat dissipation via clip or screw mounting methods. Evaluate isolation voltage requirements carefully, as the available isolation rating varies significantly depending on whether the epoxy body is mounted inside or outside the heatsink structure during assembly.

Diode Arrays Part Context

This part belongs to the Littelfuse MBR series of Schottky Barrier Rectifiers, which are engineered for commercial applications demanding high temperature stability and low forward voltage. The series utilizes silicon technology to provide superior switching characteristics compared to standard PN junction diodes, making it suitable for modern power electronics designs focused on efficiency.

Diode Arrays Replacement Considerations

Consult Littelfuse official substitution guides for verified alternatives. Generic cross-references may not match the specific guard ring ruggedness or isolation voltage characteristics defined in the original datasheet.

Diode Arrays FAQ

What is the isolation voltage rating for the MBRF20100CTP?

The isolation voltage depends on the mounting method: 4500V for clip mounting with the epoxy body away from the heatsink edge, 3500V if the body is inside the heatsink, and 1500V for screw mounting with the body inside the heatsink.

How is the average forward current rated for this device?

The device supports a total average forward current of 20A, with each leg rated for 10A under a 50% duty cycle rectangular waveform at a case temperature of 105°C.

Does the MBRF20100CTP have reverse recovery time?

No, as a Schottky barrier rectifier utilizing majority carrier conduction, it does not exhibit minority carrier storage effects or a reverse recovery time.
