SJ4025N2ATP

Overview

The Littelfuse SJ4025N2ATP is a Silicon Controlled Rectifier (SCR) from the SJxx25xx series, designed for surface mount applications. It features a rated repetitive off-state voltage of 400 V and an on-state RMS current of 12 A. The device operates within a temperature range of -40°C to +150°C and utilizes a TO-263AB-3 package. Key electrical parameters include a gate trigger voltage of 1.5 V and compliance with AEC-Q101 automotive standards.

Feature Summary

High-temperature operation capability up to 150°C
Automotive-grade reliability certified under AEC-Q101
Surface-mount design in a compact TO-263AB-3 package

Applications

Automotive power control circuits
Industrial motor drives
High-temperature rectification systems

Procurement Notes

Verify the exact part number against official Littelfuse documentation, as the specific suffix 'N2' requires confirmation of its functional impact compared to similar variants like SJ4025N1ATP. Ensure that ordering quantities align with manufacturer specifications, typically involving tube packaging for this series. Cross-reference datasheets to confirm availability and lead times directly from authorized channels.

Selection Notes

Select this component when a 400V SCR with 12A RMS current handling is required in high-temperature environments. The TO-263AB-3 package facilitates automated surface mount assembly. Verify that the 1.5V gate trigger voltage matches the driving circuit capabilities. Confirm AEC-Q101 certification is necessary for the target application's reliability standards.

Part Context

This device belongs to the SJxx25xx series of high-temperature SCRs manufactured by Littelfuse. It shares the 400V/25A family naming convention but is specified for 12A RMS operation. The series is characterized by robust performance in demanding thermal conditions, distinguishing it from standard industrial thyristors.

Replacement Considerations

Direct substitutes may include other Littelfuse SJ series devices with matching voltage and current ratings. Verify pinout compatibility and thermal characteristics before substitution. Consult official Littelfuse cross-reference guides for confirmed equivalent part numbers.
