SJ4025N1ATP

Overview

The Littelfuse SJ4025N1ATP is a Silicon Controlled Rectifier (SCR) from the SJxx25xx series, designed for high-temperature operation. It features a rated repetitive off-state voltage (VDRM) of 400 V and an on-state RMS current (It RMS) of 12 A. The device requires a gate trigger voltage (Vgt) of 1.5 V for activation. It operates within a temperature range of -40°C to +150°C and is housed in a TO-263AB-3 surface-mount package. The component holds AEC-Q101 qualification, ensuring reliability for automotive applications.

Feature Summary

AEC-Q101 qualified for automotive-grade reliability
High-temperature capability up to 150°C
Surface-mount TO-263AB-3 packaging

Applications

Automotive power control circuits
Industrial motor drives
AC/DC power conversion systems

Procurement Notes

Verify the specific suffix '1' against the manufacturer's official datasheet to confirm exact electrical tolerances and thermal characteristics. Confirm that the TO-263AB-3 package dimensions match the target PCB footprint requirements. Ensure the 400V rating aligns with the system's peak voltage stresses. Check for any recent process change notifications that may affect pinout or material composition.

Selection Notes

Select this component when a 12 A RMS SCR is required in a compact surface-mount form factor. The 400V blocking voltage suits low-to-medium voltage AC applications. The AEC-Q101 certification is essential for automotive designs. Consider the 1.5V gate trigger requirement for driver compatibility. Evaluate thermal management needs given the 150°C maximum junction temperature limit.

Part Context

This part belongs to the Littelfuse SJxx25xx series of thyristors. The series includes various voltage ratings and packages. The SJ4025N1ATP specifically denotes the 400V, 12A variant in the TO-263AB-3 package. Other variants in the series may differ in voltage, current, or package type.

Replacement Considerations

Consult Littelfuse official documentation for direct cross-references. Verify that any substitute maintains the 400V VDRM, 12A It RMS, and TO-263AB-3 package. Ensure the replacement also meets AEC-Q101 standards if used in automotive contexts.
