Diode Arrays Procurement Notes

Verify the specific package type required, as the SBR30A40CT designation corresponds to the TO-220AB case, while the SBR30A40CTFP denotes the ITO-220AB variant. Confirm compliance requirements such as RoHS and halogen-free status, noting that green molding compound versions require a specific suffix. Ensure thermal management aligns with the specified junction-to-case thermal resistance values for the selected package.

Diode Arrays Selection Notes

Select this component for applications requiring high current handling at low voltage drops. The TO-220AB package provides a thermal resistance of 2°C/W per leg, suitable for efficient heat dissipation. Consider derating the average forward current by 20% if used with capacitive loads. Verify that the operating temperature range of -65°C to +150°C meets the environmental demands of the target system.

Diode Arrays Part Context

This part belongs to the SBR30 series of Super Barrier Rectifiers from Diodes Incorporated. It shares the same core technology and electrical characteristics as other variants in the family, differing primarily in peak repetitive reverse voltage ratings and physical package configurations. The series is designed to replace traditional Schottky diodes in various power supply applications.

Diode Arrays FAQ

What is the difference between the SBR30A40CT and SBR30A40CTFP packages?

The SBR30A40CT uses the TO-220AB case, while the SBR30A40CTFP uses the ITO-220AB case. The ITO-220AB variant offers higher isolation voltage (2000 VAC) and has a different thermal resistance value compared to the TO-220AB.

How does the SBR30A40CT handle capacitive loads?

When used with capacitive loads, the average forward current must be derated by 20% to ensure reliable operation within the specified thermal limits.

Is the SBR30A40CT compliant with RoHS directives?

Yes, the standard SBR30A40CT is lead-free and RoHS compliant. A green molding compound version is also available by adding the '-G' suffix to the part number.
