Diode Arrays Procurement Notes

Verify the exact part number suffix, as standard datasheets typically list MBR1545CT without the HE3/45 designation. Confirm RoHS compliance status and lead times directly with the manufacturer or authorized distributors, as availability may vary. Ensure the procurement documentation matches the specific TO-220AB package requirements for your assembly process.

Diode Arrays Selection Notes

Select this component for designs requiring a 45 V rating with 15 A continuous current handling in a through-hole format. The TO-220AB package facilitates effective heat dissipation for high-current applications. Consider the 175°C maximum junction temperature for thermal management calculations in enclosed environments.

Diode Arrays Part Context

This device belongs to the MBR15xxCT series of Schottky barrier rectifiers from Vishay. These components are engineered for general-purpose rectification in power supply circuits where low forward voltage drop and fast switching speeds are critical. The series offers various voltage ratings to suit different input and output requirements.

Diode Arrays Replacement Considerations

Direct substitutes include the STPS15L45CT from STMicroelectronics and the MBR1545CT from other manufacturers offering identical 15 A, 45 V specifications in a TO-220AB package. Verify pinout compatibility and thermal resistance values before substitution.
