Overview
The Littelfuse SJ4025R2TP is a Silicon Controlled Rectifier (SCR) designed for high-temperature applications. It features a rated repetitive off-state voltage of 400 V and an on-state RMS current capability of 25 A. The device utilizes a TO-220AB non-isolated package with three pins. It operates within a temperature range from -40°C to +150°C. Key electrical parameters include a gate trigger voltage of 1.5 V and a holding current maximum of 100 mA. The component is qualified under AEC-Q101 standards, ensuring reliability for automotive and industrial environments.
Feature Summary
- High-temperature operation capability up to 150°C
- AEC-Q101 qualification for automotive reliability
- Standard recovery thyristor characteristics
Applications
- Automotive power control systems
- Industrial motor drives
- High-temperature rectification circuits
Procurement Notes
Verify the specific datasheet version when ordering, as Littelfuse may update specifications over time. Confirm that the TO-220AB package matches your PCB footprint requirements. Ensure thermal management solutions are adequate for the 25 A RMS current rating in your specific application environment. Check for any recent product change notifications that might affect pinout or material composition.
Selection Notes
Select this component when a robust SCR with high thermal tolerance is required. The 400 V rating suits medium-voltage AC control applications. Compare against other SJ series devices if higher voltage ratings like 600 V are needed. Consider the non-isolated package type for mounting constraints. Verify gate trigger requirements against your driving circuit capabilities.
Part Context
This part belongs to the SJxx25xx series of SCRs from Littelfuse. These components are engineered for durability in demanding electronic environments. The series offers various voltage ratings while maintaining consistent current handling capabilities. The SJ4025R2TP specifically targets applications requiring reliable switching at elevated temperatures.
Replacement Considerations
Direct substitutes may include other Littelfuse SCRs with identical 400 V and 25 A ratings in TO-220 packages. Cross-reference with QJ4025RH5TP for triac alternatives if bidirectional control is acceptable. Always verify pin compatibility and thermal performance before substituting.
