SBR1040CT

Diode Arrays Overview

The SBR1040CT is a 10A Super Barrier Rectifier (SBR) from Diodes Incorporated, available in TO220AB and ITO220AB packages. It features a peak repetitive reverse voltage of 40V and an average rectified output current of 10A per leg. The device exhibits a typical forward voltage drop of 0.46V at 5A and 25°C, rising to 0.55V at 125°C. Leakage current is typically 0.5mA at 40V reverse bias and 25°C. Thermal resistance is 2°C/W for TO220AB and 4°C/W for ITO220AB junction-to-case.

Diode Arrays Feature Summary

• Patented Super Barrier Rectifier technology providing low forward voltage drop and excellent high-temperature stability.
• Soft, fast switching capability designed to minimize electromagnetic interference.
• Available in lead-free, RoHS compliant 'Green' packages that are halogen and antimony free.

Diode Arrays Applications

• High-frequency DC/DC converters
• Free-wheeling diodes in power supplies
• Polarity protection circuits

Diode Arrays Procurement Notes

Verify the specific package variant required, as the standard SBR1040CT uses TO220AB while the SBR1040CTFP uses ITO220AB. Confirm compliance with environmental directives such as RoHS 3 if halogen-free status is mandatory. Ensure thermal management design accounts for the specified junction-to-case thermal resistance values during operation.

Diode Arrays Selection Notes

Select this component for applications requiring high efficiency and reduced heat generation due to its low forward voltage characteristics. Consider the ITO220AB variant if electrical isolation between the terminal and heatsink is necessary, as it supports up to 2000VAC isolation voltage compared to the non-isolated TO220AB option.

Diode Arrays Part Context

This part belongs to Diodes Incorporated's SBR series, utilizing proprietary Super Barrier Rectifier technology. This technology combines the low forward voltage of Schottky diodes with the high-temperature reliability of silicon PN junctions, offering a superior alternative to traditional rectifiers in modern power conversion designs.

Diode Arrays Replacement Considerations

For automotive applications requiring specific change control or AEC-Q qualification, refer to the related Q-suffix parts listed on the manufacturer's website. Standard industrial versions do not carry these automotive certifications.

Diode Arrays FAQ

Does the SBR1040CT provide electrical isolation between the terminal and heatsink?

No, the standard TO220AB package does not offer isolation. Electrical isolation is only available in the ITO220AB package variant, which supports 2000VAC isolation voltage.

What is the maximum operating junction temperature for this device?

The operating and storage temperature range extends from -65°C to +150°C.

How does the forward voltage drop change with temperature?

The typical forward voltage drop increases with temperature, rising from 0.46V at 25°C to 0.55V at 125°C when tested at 5A.
