SJ4025R2ATP

Overview

The Littelfuse SJ4025R2ATP is a silicon-controlled rectifier (SCR) designed for high-power switching applications. It features a rated repetitive off-state voltage of 400 V and an on-state RMS current capacity of 25 A. The device utilizes a standard recovery configuration suitable for industrial environments. It operates within a temperature range of -40°C to +150°C and meets AEC-Q101 automotive qualification standards. The component is housed in a TO-220AB through-hole package, providing robust mechanical stability and thermal dissipation capabilities for demanding power electronics designs.

Feature Summary

Automotive-grade reliability with AEC-Q101 qualification
High current handling capability at 25 A RMS
Wide operating temperature range up to 150°C
Standard recovery thyristor construction

Applications

Industrial motor control systems
Power supply circuits
Heating control applications
General purpose AC/DC switching

Procurement Notes

Verify the specific suffix 'R2' corresponds to the required package variant during sourcing. Confirm that the manufacturer's latest datasheet aligns with the intended thermal management design. Ensure compatibility with gate drive requirements specified in the official documentation before finalizing procurement orders.

Selection Notes

Select this component when a 400 V blocking voltage and 25 A continuous current are required in a through-hole format. Consider the AEC-Q101 certification if the application demands automotive-grade durability. Evaluate thermal resistance parameters against the system's heat sink capabilities to ensure safe operation within the specified temperature limits.

Part Context

This part belongs to the SJxx25xxA series of power thyristors from Littelfuse. The series offers various voltage and current ratings packaged in different form factors. The SJ4025R2ATP specifically addresses needs for medium-to-high power switching where through-hole mounting and automotive qualification are critical design constraints.

Replacement Considerations

Consult official Littelfuse cross-reference documents for verified substitutes. Ensure any replacement maintains identical voltage, current, and package specifications.
