Overview
The Littelfuse SK010DTP is a silicon-controlled rectifier (SCR) designed for high-voltage power control applications. It features a maximum repetitive peak off-state voltage of 1000 V and a continuous on-state current rating of 10 A. The device is housed in a DO-201AD axial leaded package, suitable for through-hole mounting on printed circuit boards. Key electrical characteristics include a gate trigger voltage typically ranging from 1.5 V to 4.0 V and a holding current of 30 mA. The component is rated for operation at junction temperatures up to 125 °C and supports surge currents up to 100 A for half-cycle sine waves at 60 Hz.
Feature Summary
- High voltage blocking capability for robust power switching
- Robust surge current handling for industrial environments
- Standard axial leaded package for easy PCB integration
Applications
- Industrial motor control systems
- Solid-state relays
- Power supply regulation circuits
- Heating element control
Procurement Notes
Verify the specific suffix 'DTP' against the official Littelfuse datasheet to confirm tape-and-reel packaging specifications and lot traceability requirements. Ensure that the ordering quantity aligns with the manufacturer's standard reel size constraints. Confirm compliance with RoHS directives if required by the end application standards.
Selection Notes
Select this component when a 1000 V blocking voltage and 10 A continuous current are required in an axial package. Evaluate the thermal management needs for the DO-201AD case to ensure the junction temperature remains within the 125 °C limit under expected load conditions. Compare gate trigger characteristics against the driving circuit capabilities to ensure reliable turn-on.
Part Context
The SK series represents Littelfuse's line of general-purpose silicon-controlled rectifiers. These devices are engineered for reliability in demanding power electronics applications. The SK010DTP specifically targets scenarios requiring moderate current handling with high voltage isolation in a traditional leaded form factor.
Replacement Considerations
Consult Littelfuse cross-reference guides for equivalent SCR part numbers with matching voltage and current ratings. Verify pinout compatibility and package dimensions before substituting with components from other manufacturers to ensure mechanical fit and electrical performance equivalence.
