MBR1090CT

Diode Arrays Overview

The MBR1090CT is a dual Schottky barrier rectifier from the Taiwan Semiconductor MBR1035CT series, housed in a TO-220AB package. It features two internal diodes configured as a common cathode arrangement. The device supports a repetitive peak reverse voltage (VRRM) of 90 V and an average forward current (IF) of 10 A per diode. It withstands a surge peak forward current (IFSM) of 120 A. Electrical characteristics include a maximum forward voltage of 0.85 V at 5 A and 0.95 V at 10 A (typical). The junction temperature range spans from -55°C to +150°C.

Diode Arrays Procurement Notes

Verify the specific ordering code suffix when purchasing. The standard 'MBR1090CT' denotes the base component, while the 'H' suffix indicates AEC-Q101 automotive qualification. Confirm the package type is TO-220AB and check packing details, which are typically supplied in tubes of 50 units. Ensure the supplier documentation matches the O2104 datasheet version for accurate specifications.

Diode Arrays Selection Notes

Select this component for circuits requiring a 90 V reverse voltage rating with a 10 A continuous current capacity. The TO-220AB package facilitates heat dissipation through the mounting tab. Consider the thermal resistance of 1.5 °C/W for heatsinking requirements. This part is suitable for low-voltage, high-frequency applications where low forward voltage drop is critical for system efficiency.

Diode Arrays Part Context

This device belongs to the MBR1035CT series, which covers voltage ratings from 35 V to 200 V. All members share identical current ratings and package dimensions. The MBR1090CT specifically targets applications needing 90 V blocking capability. Other series members include MBR1035CT, MBR1045CT, MBR1050CT, MBR1060CT, MBR10100CT, MBR10150CT, and MBR10200CT.

Diode Arrays Replacement Considerations

Direct substitutes within the same series include MBR1060CT (60 V) or MBR10100CT (100 V), provided the voltage rating meets the circuit requirements. Cross-manufacturer equivalents must match the 10 A current, 90 V minimum reverse voltage, TO-220AB package, and common cathode configuration.

Diode Arrays FAQ
