SJ4020N1ATP

Overview

The Littelfuse SJ4020N1ATP is a Silicon Controlled Rectifier (SCR) belonging to the SJxx20xx series, designed for high-temperature applications. It features a rated repetitive off-state voltage (VDRM) of 400 V and an on-state RMS current (It RMS) of 20 A. The device operates within a temperature range of -40°C to +150°C. Key electrical parameters include a forward voltage (Vf) of 1.6 V, gate trigger voltage (Vgt) of 1.5 V, and gate trigger current (Igt) of 35 mA. It utilizes a TO-263AB-3 surface-mount package and holds AEC-Q101 qualification.

Feature Summary

AEC-Q101 qualified for automotive reliability standards
High junction temperature capability up to 150°C
Surface-mount TO-263AB-3 package design

Applications

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

Procurement Notes

Verify the specific suffix 'N1' against official Littelfuse documentation to confirm exact gate trigger characteristics and packaging details. Ensure the component matches the required AEC-Q101 certification if used in automotive contexts. Cross-reference the datasheet for thermal management requirements associated with the TO-263AB-3 package.

Selection Notes

Select this SCR when a 400V rating and 20A continuous current are required in a surface-mount form factor. Compare gate trigger currents with similar models like SJ4020NATP or SJ4020N1RP to ensure compatibility with the driving circuit. Consider the thermal resistance of the TO-263AB-3 package for heat dissipation needs.

Part Context

This component is part of the Littelfuse SJxx20xx series of thyristors. The series offers various voltage and current ratings in different packages. The SJ4020N1ATP specifically targets applications requiring robust performance in harsh environments, leveraging the company's expertise in circuit protection and power control.

Replacement Considerations

Check Littelfuse datasheets for direct pin-compatible alternatives within the SJ4020 series. Verify that any substitute maintains the same 400V VDRM, 20A It RMS, and TO-263AB-3 package dimensions.
