SJ4020R1ATP

Overview

The Littelfuse SJ4020R1ATP is a Silicon Controlled Rectifier (SCR) belonging to the SJxx20xx series, designed for high-temperature industrial applications. It features a rated repetitive off-state voltage of 400 V and an RMS on-state current of 20 A. The device operates within a temperature range of -40°C to +150°C and utilizes a TO-220-2 package for through-hole mounting. Key electrical characteristics include a forward voltage of 1.6 V, a gate trigger voltage of 1.5 V, and a gate trigger current of 10 mA. It exhibits a non-repetitive peak on-state current capability of 300 A and maintains a maximum holding current of 35 mA.

Feature Summary

AEC-Q101 qualified for automotive reliability standards
High junction temperature operation up to 150°C
Robust surge handling with 300 A non-repetitive current capacity

Applications

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

Procurement Notes

Verify the specific suffix 'R1' against official Littelfuse documentation to confirm exact gate trigger parameters, as variations exist within the SJ4020 family. Ensure the procurement channel provides valid traceability for AEC-Q101 certified components. Confirm lead times and minimum order quantities directly with authorized distributors, as these are subject to change based on production schedules.

Selection Notes

Select this component when automotive-grade reliability is required alongside high thermal performance. The 400V rating suits low-voltage AC/DC conversion tasks. Compare gate trigger current requirements against the driving circuit capabilities. Ensure the TO-220-2 package fits the mechanical constraints of the target assembly.

Part Context

This part belongs to the SJxx20xx series of thyristors manufactured by Littelfuse. The series is characterized by its ability to operate at elevated temperatures and its qualification for automotive environments. Similar parts in the lineup may differ in packaging or specific gate sensitivities.

Replacement Considerations

Cross-reference with SJ4020L1TP or SJ4020NRP only if package type and electrical ratings match exactly. Verify that substitute devices meet the same AEC-Q101 qualification level and thermal specifications.
