SDT40100CT

Diode Arrays Overview

The SDT40100CT is a Trench Schottky Rectifier manufactured by Diodes Incorporated, available in TO220AB and ITO220AB packages. It features a dual common cathode configuration with two independent legs. Each leg supports a peak repetitive reverse voltage of 100V and an average rectified output current of 20A, totaling 40A per device. The maximum forward voltage drop is 0.79V at 20A and +25°C. Non-repetitive peak forward surge current reaches 200A. Operating and storage temperature ranges span from -55°C to +150°C.

Diode Arrays Feature Summary

• Low forward voltage drop for reduced power loss
• Excellent high-temperature stability with low reverse leakage
• Soft and fast switching capability
• Lead-free finish compliant with RoHS directives

Diode Arrays Applications

• DC-DC converters
• AC-DC adaptors
• Freewheel diode circuits
• Blocking diode applications

Diode Arrays Procurement Notes

Verify the specific package variant required, as the SDT40100CT designation covers both standard TO220AB and isolated ITO220AB configurations. Confirm compliance requirements against EU RoHS and REACH standards before procurement. Ensure thermal management aligns with the specified junction-to-case thermal resistance values for the selected package type during system integration.

Diode Arrays Selection Notes

Select this component when designing circuits requiring high current handling up to 40A total with low conduction losses. The 100V rating suits lower voltage DC systems. Evaluate thermal dissipation needs carefully, as the device operates reliably up to 150°C junction temperature. Consider the ITO220AB variant if electrical isolation between the heatsink and circuit ground is necessary for safety or noise reduction.

Diode Arrays Part Context

This part belongs to Diodes Incorporated's Trench Schottky Rectifier series, utilizing advanced trench technology to minimize forward voltage while maintaining robust reverse blocking capabilities. The product line targets efficiency improvements in power conversion stages where heat generation must be minimized. It represents a mature silicon-based solution for general-purpose rectification tasks.

Diode Arrays FAQ

What is the difference between the SDT40100CT and SDT40100CTFP?

The SDT40100CT uses a standard TO220AB package where the metal tab is electrically connected to one of the terminals. The SDT40100CTFP utilizes an ITO220AB package, providing electrical isolation between the metal tab and the internal circuitry.

How does the forward voltage change with temperature?

The forward voltage decreases as temperature increases. At 20A, the maximum forward voltage drops from 0.79V at +25°C to 0.73V at +125°C.

Is this component suitable for automotive applications?

Standard versions are not explicitly qualified for automotive use. For automotive applications requiring AEC-Q100/101/104/200 qualification and PPAP capability, direct contact with Diodes Incorporated is required.
