Overview
The SJ4025L1TP is a Silicon Controlled Rectifier (SCR) manufactured by Littelfuse Inc., designed for high-temperature applications. It features a rated repetitive off-state voltage of 400 V and an on-state RMS current of 25 A. The device operates within a temperature range of -40°C to +150°C. It utilizes a TO-220-2 package with through-hole mounting style. Key electrical parameters include a gate trigger voltage of 1.5 V. The component is qualified under the AEC-Q101 standard, indicating suitability for automotive environments.
Feature Summary
- High junction temperature capability for demanding thermal environments
- Automotive qualification ensuring reliability in vehicle applications
- Through-hole mounting for robust mechanical integration
Applications
- Automotive power control systems
- Industrial motor drives
- High-temperature rectification circuits
Procurement Notes
Verify the specific voltage rating configuration during procurement, as external sources may reference conflicting values such as 600V. Confirm the package type matches the required board layout, specifically the TO-220-2 form factor. Ensure the supplier provides documentation confirming AEC-Q101 qualification status if automotive compliance is mandatory for the project.
Selection Notes
Select this component when a 400V SCR with 25A continuous current handling is required in a through-hole package. Consider the high operating temperature limit of 150°C for designs with limited cooling. The AEC-Q101 qualification makes it appropriate for automotive use cases where standard industrial components may not suffice due to environmental stress requirements.
Part Context
This part belongs to the SJ series of SCRs from Littelfuse, which are engineered for high-temperature performance. The series includes variants with different voltage ratings and package options. The SJ4025L1TP specifically addresses the need for reliable switching in automotive and industrial sectors requiring robust thyristor solutions.
Replacement Considerations
Cross-reference with other 400V, 25A SCRs in TO-220 packages. Verify pinout compatibility and thermal characteristics before substitution. Check datasheets for equivalent gate trigger specifications to ensure circuit stability.
