Overview
The Littelfuse SJ4025N1ARP is an automotive-grade 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 of 12 A. The device operates within a junction temperature range of -40°C to +150°C and is qualified under the AEC-Q101 standard. Packaged in a surface-mount TO-263 (D2PAK) format, it offers robust surge capability up to 350 A at 60 Hz half cycle.
Feature Summary
- AEC-Q101 qualified for automotive reliability standards
- High junction temperature operation up to 150°C
- Halogen-free and RoHS compliant construction
- Surface-mount TO-263 package for automated assembly
Applications
- Automotive ignition systems
- Industrial motor control circuits
- High-temperature power switching applications
Procurement Notes
Verify the specific suffix 'ARP' against official Littelfuse documentation to confirm the exact thermal and electrical specifications. Ensure that the required surge current ratings and gate trigger parameters align with the target circuit design before finalizing procurement orders.
Selection Notes
Select this component when high-temperature stability and automotive qualification are mandatory. The TO-263 package suits space-constrained PCB layouts requiring surface-mount technology. Confirm that the 12 A RMS current rating meets the continuous load requirements of the application.
Part Context
This part belongs to the Littelfuse SJ series of high-temperature SCRs. It shares the 400V blocking voltage characteristic with other variants in the family but differs in packaging and specific thermal handling capabilities defined by the ARP suffix designation.
Replacement Considerations
Cross-reference with SJ4025N1ATP for similar electrical ratings but verify package compatibility. Check Q4025N5RP only if bidirectional triac functionality is acceptable, noting the significant difference in device type and pinout.
