Scrs 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.

Scrs 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.

Scrs 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.

Scrs 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.
