Diode Arrays Procurement Notes

Verify the component authenticity by checking for the specific marking corresponding to the type number on the package surface. Ensure the ordering suffix matches the required packing configuration, as the BP suffix indicates bulk packaging containing 1000 pieces per box. Confirm compliance requirements such as lead-free finish and RoHS status directly from the manufacturer's documentation before procurement.

Diode Arrays Selection Notes

Select this component when designing circuits requiring a 120 V blocking voltage and 20 A continuous current handling in a TO-220AB package. Consider the thermal resistance of 2.2°C/W junction-to-case for heat sink sizing. Evaluate the derating curve for average forward current relative to case temperature to ensure operation within the 150°C maximum junction temperature limit under expected load conditions.

Diode Arrays Part Context

This part belongs to the MBR20 series of high voltage Schottky rectifiers produced by Micro Commercial Components. The series utilizes silicon technology optimized for high-speed switching and low reverse leakage. The TO-220AB through-hole package facilitates mounting on printed circuit boards or direct attachment to heatsinks for thermal management in power supply designs.

Diode Arrays Replacement Considerations

Cross-reference with other manufacturers offering dual common cathode Schottky rectifiers with identical 120 V reverse voltage and 20 A forward current ratings in the TO-220AB package. Verify pinout compatibility and thermal resistance specifications to ensure functional equivalence without redesigning the PCB footprint.
