SDUR1030CT

Diode Arrays Overview

The SDUR1030CT is a general-purpose diode array manufactured by SMC Diode Solutions, designed for surface-mount and through-hole applications. It features a single pair of common cathode configuration housed in a TO-220-3 package. The device operates with a maximum DC reverse voltage (Vr) of 300 V and exhibits a forward voltage (Vf) of 1.3 V at a forward current (If) of 5 A. Key electrical characteristics include a reverse recovery time (trr) of 45 ns and a reverse leakage current of 30 µA at 300 V. The component supports a junction temperature range from -55°C to 150°C and falls under the fast recovery category with speeds less than or equal to 500 ns.

Diode Arrays Procurement Notes

Verify the specific package variant during procurement, as the SDUR1030CT designation may correspond to different physical packages such as TO-220AB or D2PAK depending on the manufacturer's suffix conventions. Confirm that the received components match the required pinout and thermal pad specifications for your PCB layout. Ensure compliance with RoHS3 standards if environmental regulations apply to your assembly process. Cross-reference the datasheet revision date to ensure access to the most recent electrical limits and handling instructions.

Diode Arrays Selection Notes

Select the SDUR1030CT when designing circuits that require a 300 V blocking capability combined with fast switching speeds. This component is suitable for applications where space constraints favor integrated dual-diode solutions over discrete parts. Consider the thermal resistance of the chosen package variant to ensure adequate heat dissipation at expected load currents. Evaluate the reverse leakage current specifications against your system's sensitivity to off-state losses.

Diode Arrays Part Context

This component belongs to the SDUR series of fast recovery diode arrays from SMC Diode Solutions. It shares functional similarities with other models in the lineup, such as the SDURB1030CT and SDURF1030CT, which offer comparable electrical ratings but differ in package type. The series is engineered for general-purpose rectification tasks, providing a balance between voltage rating, speed, and current handling capacity for various industrial and consumer electronics applications.

Diode Arrays Replacement Considerations

Potential substitutes include the SDURB1030CT for surface-mount D2PAK implementations or the SDURF1030CT for alternative through-hole configurations. Verify that any replacement part maintains the same 300 V reverse voltage rating and 45 ns reverse recovery time to ensure circuit compatibility. Check pinout alignment and thermal characteristics before integrating alternative components into existing designs.
