CTNS-6603S

Diode Arrays Overview

The CTNS-6603S is a fast recovery high power diode manufactured by Sanken Electric. It features a peak repetitive reverse voltage (VRM) of 300 V and an average forward current (IF(AV)) rating of 60 A. The device exhibits a typical forward voltage drop (VF) of 0.95 V at 30 A, with a maximum of 1.2 V. Its reverse recovery time (trr) is limited to 100 ns under specified test conditions. The component utilizes a TO-247-3L package, providing a thermal resistance from junction to case of 1.0 °C/W. It supports a junction temperature range from -40 °C to 150 °C.

Diode Arrays Procurement Notes

Verify the specific revision number on the datasheet before procurement, as Sanken may update specifications without notice. Confirm that the TO-247-3L package dimensions match your PCB footprint requirements. Ensure sourcing channels provide genuine Sanken products to avoid counterfeit components. Check for any RoHS compliance documentation if required for your manufacturing process. Review the operating precautions regarding screw torque and heatsink mounting flatness during integration.

Diode Arrays Selection Notes

Select this component when designing circuits requiring a 300 V reverse voltage rating and up to 60 A average forward current. Consider the 100 ns reverse recovery time for applications demanding fast switching speeds. Evaluate the thermal management capabilities based on the 1.0 °C/W junction-to-case thermal resistance. Ensure the operating environment stays within the -40 °C to 150 °C junction temperature limits. Verify compatibility with PFC topologies supporting both discontinuous and continuous conduction modes.
