SJ4020N1TP

Overview

The Littelfuse SJ4020N1TP is a Silicon Controlled Rectifier (SCR) belonging to the SJxx20xx series, designed for high-temperature operation. 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. Key electrical parameters include a forward voltage of 1.6 V, a gate trigger voltage of 1.5 V, and a gate trigger current of 35 mA. It utilizes a TO-263AB-3 surface mount package with three terminals.

Feature Summary

High-temperature capability up to 150°C
Surface mount construction for automated assembly
AEC-Q101 automotive qualification

Applications

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

Procurement Notes

Verify the specific suffix against official Littelfuse documentation to confirm pinout and thermal characteristics. Ensure the ordering part number matches the required package type exactly. Confirm that the component meets all necessary regulatory standards for the intended end-use application before finalizing procurement.

Selection Notes

Select this component when a surface mount SCR with 400V blocking capability is required. Verify that the PCB layout supports the TO-263AB-3 footprint. Consider the 35 mA gate trigger current requirement for the driving circuit design. Ensure the thermal management solution accommodates the 150°C maximum junction temperature limit.

Part Context

This device is part of the Littelfuse SJxx20xx family of thyristors. The family offers various voltage ratings and packaging options. The SJ4020N1TP specifically provides a surface mount alternative to through-hole devices in the same series, maintaining similar electrical performance metrics while enabling compact board designs.

Replacement Considerations

Consult the Littelfuse SJxx20xx datasheet for direct pin-compatible alternatives. Verify that any substitute maintains the 400V rating and 20A current capacity. Check if the replacement requires different gate drive characteristics.
