SJ4025L2ATP

Overview

The Littelfuse SJ4025L2ATP is a standard recovery Silicon Controlled Rectifier (SCR) designed for high-temperature automotive applications. It features a 400 V repetitive peak off-state voltage and an RMS on-state current of 12 A. The device operates within a junction temperature range of -40°C to +150°C and holds AEC-Q101 qualification. Packaged in a TO-220AB-3 isolated tab configuration, it supports surface mount or through-hole installation with a gate trigger voltage of 1.5 V.

Feature Summary

AEC-Q101 qualified for automotive reliability standards
High thermal stability with maximum junction temperature of 150°C
Standard phase control design for robust switching performance

Applications

Automotive heating systems
Motor speed control circuits
Phase control applications requiring high surge capability

Procurement Notes

Verify the specific package variant against the datasheet, as the model number indicates a TO-220 form factor distinct from other series members. Confirm AEC-Q101 compliance requirements for your target application. Ensure thermal management solutions support the 150°C operating limit. Check lead times due to potential automotive supply chain constraints.

Selection Notes

Select this component when automotive-grade SCR reliability is required alongside high-temperature operation. Compare surge current ratings against load requirements. Consider the TO-220 footprint for board space versus alternative packages. Validate gate trigger characteristics against driver circuit capabilities.

Part Context

This part belongs to the SJxx25xxA series of low-power SCRs from Littelfuse. The series offers voltages up to 1200V and includes various package options like TO-220 and TO-263. The SJ4025L2ATP specifically targets the 400V, 12A RMS segment with automotive certification.

Replacement Considerations

Cross-reference with SJ4025N1ATP for surface-mount TO-263 compatibility if PCB layout allows. Verify pinout and thermal resistance differences between TO-220 and TO-263 packages before substitution.
