MBR1050CT

Diode Arrays Overview

The MBR1050CT is a dual common cathode Schottky barrier rectifier manufactured by Diodes Incorporated. It features two independent silicon elements within a single TO-220AB package. Each leg supports an average forward current of 5 A, totaling 10 A for the device. The repetitive peak reverse voltage is rated at 50 V. Maximum forward voltage drop is 0.65 V at 25°C and 0.75 V at 125°C junction temperature. Peak reverse current is limited to 0.1 mA at 25°C.

Diode Arrays Feature Summary

• Guard ring die construction provides transient protection capabilities
• High surge current capability suitable for demanding switching applications

Diode Arrays Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging type and shipping quantity. Ensure the component meets required environmental standards such as RoHS and halogen-free specifications. Confirm thermal resistance values match the intended heat sink design. Check for AEC-Q101 qualification if automotive reliability is required. Validate marking codes on the physical device against the datasheet schematic.

Diode Arrays Selection Notes

Select this component when a dual common cathode configuration is required for synchronous rectification or free-wheeling applications. The TO-220AB package offers robust mechanical mounting and thermal dissipation for through-hole implementations. Consider the 50 V rating relative to the system's peak reverse voltage requirements. Evaluate the forward voltage characteristics against efficiency targets at expected operating currents and temperatures.

Diode Arrays Part Context

This part belongs to the MBR1040CT-MBR1060CT-I series of 10A Schottky Barrier Rectifiers from Diodes Incorporated. The series includes variants with different reverse voltage ratings ranging from 40 V to 60 V per leg. All members share identical current handling capabilities and package dimensions while differing in breakdown voltage and forward voltage specifications.

Diode Arrays Replacement Considerations

MBR1040CT and MBR1045CT are direct substitutes within the same series offering lower reverse voltage ratings. MBR1060CT-I provides a higher 60 V rating with slightly increased forward voltage drop. Verify pinout compatibility and thermal performance when substituting across the series.
