Overview
The Littelfuse SJ4025N2ARP is a Silicon Controlled Rectifier (SCR) designed for surface mount applications. It features a rated repetitive peak off-state voltage (VDRM) of 400 V and an on-state RMS current (ITRMS) of 25 A. The device operates within a junction temperature range of -40°C to +150°C, supporting high-temperature environments. Key gate parameters include a trigger voltage (VGT) of 1.5 V and a trigger current (IGT) of 10 mA. The component is housed in a D2PAK-2 (TO-263-2) package and holds AEC-Q101 qualification for automotive reliability standards.
Feature Summary
- High junction temperature capability up to +150°C for robust thermal performance
- AEC-Q101 qualified for automotive electronic applications
- Surface mount D2PAK-2 package design for automated assembly
Applications
- Automotive power control circuits
- Industrial motor drive systems
- AC/DC power switching applications
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct pinout and electrical characteristics. Confirm that the AEC-Q101 qualification status meets the target application's reliability requirements. Check for any recent product change notices regarding package dimensions or material composition before finalizing the design.
Selection Notes
Select this component when a 400 V blocking voltage and 25 A continuous current rating are required in a surface mount format. Ensure the circuit design accommodates the specified gate trigger current of 10 mA. Consider the thermal management capabilities provided by the TO-263-2 tab for heat dissipation in high-power scenarios.
Part Context
This part belongs to the Littelfuse SJ series of SCRs, which offers a range of voltages up to 600 V and currents from 4 A to 40 A. The series is characterized by high junction temperature ratings and is widely used in industrial and automotive sectors requiring reliable thyristor switching solutions.
Replacement Considerations
Consult the official Littelfuse substitution guide for verified alternatives. Cross-reference key parameters such as VDRM, ITRMS, and package type to ensure functional compatibility without compromising system safety or performance.
