SJ4032NARP

Scrs Overview

The Littelfuse SJ4032NARP is a Silicon Controlled Rectifier (SCR) designed for high-temperature environments. It features a rated repetitive off-state voltage of 400 V and an RMS on-state current capability of 32 A. The device operates within a junction temperature range from -40 °C to +150 °C. Key electrical parameters include a maximum gate trigger voltage of 1.5 V, a gate trigger current of 35 mA, and a forward voltage drop of 1.6 V at rated current. The component utilizes a TO-263AB-3 surface mount package and meets AEC-Q101 automotive qualification standards.

Scrs Feature Summary

• High thermal stability enabling operation up to +150 °C junction temperature
• Automotive-grade reliability certified under AEC-Q101 standards
• Surface-mount construction in a compact TO-263AB-3 package

Scrs Applications

• Solid state relays

Scrs Procurement Notes

Verify the specific suffix against official Littelfuse documentation to confirm exact electrical tolerances and packaging configurations. Confirm availability through authorized distributors as supply levels fluctuate. Ensure the selected variant matches the required thermal management and mounting specifications for the target application design.

Scrs Selection Notes

Select this component when a robust SCR with high surge current handling and elevated temperature tolerance is required. Compare the 32 A RMS rating against circuit load requirements. Verify that the TO-263AB-3 package fits the PCB layout constraints. Ensure the 400 V blocking voltage exceeds the peak line voltage in the intended application.

Scrs Part Context

This part belongs to the Littelfuse SJ series of high-temperature SCRs. The series provides solutions for demanding power control applications requiring reliable switching performance. The SJ4032NARP specifically addresses needs for higher current capacity compared to lower-rated variants in the same family.

Scrs Replacement Considerations

Consult Littelfuse datasheets for direct cross-references. Verify pinout compatibility and thermal resistance characteristics before substituting with other manufacturers' devices.
