Diode Arrays Procurement Notes

Verify the specific ordering code suffix when purchasing. The standard part number denotes the base component, while an 'H' prefix indicates AEC-Q101 qualification. Confirm compliance with RoHS directives and halogen-free requirements according to IEC 61249-2-21 definitions during procurement to ensure alignment with project specifications.

Diode Arrays Selection Notes

Select this component for applications requiring a 90 V blocking voltage and 30 A continuous current in a through-hole TO-247AD package. Consider the 1.4 °C/W thermal resistance for heatsinking calculations. Ensure the operating environment does not exceed the 150 °C maximum junction temperature limit.

Diode Arrays Part Context

This component belongs to the MBR30xxPT series from Taiwan Semiconductor, which covers voltage ratings from 35 V to 200 V. All members share identical mechanical dimensions and current ratings, differing primarily in their breakdown voltage specifications. The series utilizes silicon technology optimized for high-frequency switching applications.

Diode Arrays Replacement Considerations

Cross-reference with other manufacturers offering 30 A, 90 V Schottky rectifiers in the TO-247AD package. Verify that substitute parts meet or exceed the 200 A surge current rating and 150 °C junction temperature limits before implementation.
