Overview
The Littelfuse S2065KTP is a standard recovery silicon controlled rectifier (SCR) designed for power control and switching applications. It features a 200 V off-state voltage rating and supports a 65 A RMS on-state current. The device operates with a maximum gate trigger voltage of 2 V and a maximum gate trigger current of 50 mA. It has a maximum average on-state current of 41 A and a maximum on-state voltage drop of 1.8 V. Packaged in an electrically isolated TO-218 through-hole configuration, it serves as a unidirectional switch for phase control tasks.
Feature Summary
- Standard recovery SCR design optimized for reliable power switching
- Electrically isolated package construction for safety
- Low gate trigger requirements for efficient control circuitry
Applications
- Phase control applications
- Heating system controls
- Motor speed controls
Procurement Notes
Verify the specific suffix 'KTP' against the manufacturer's official documentation to confirm the exact pinout, isolation specifications, and thermal characteristics associated with this package variant. Ensure that the 200V rating aligns with the peak inverse voltage requirements of the target circuit design before finalizing procurement.
Selection Notes
Select this component when a low-voltage, high-current thyristor is required for AC phase control. The 200V rating limits its use to lower voltage mains or secondary side applications. Consider the TO-218 isolated tab for mounting on heatsinks without electrical shorting risks, ensuring adequate thermal management for the 41A average current capability.
Part Context
This part belongs to the Littelfuse Low Power SCR series, which offers devices up to 1200V. These SCRs are engineered as excellent unidirectional switches specifically for phase control applications. The series provides robust performance for industrial and consumer electronics requiring precise power regulation.
Replacement Considerations
Consult Littelfuse official cross-reference guides for compatible alternatives within the same voltage and current class. Verify that any substitute maintains the TO-218 isolated package form factor and standard recovery characteristics to ensure mechanical and electrical compatibility.
