T600141804BT

Scrs Overview

The T600141804BT is a phase control Silicon Controlled Rectifier (SCR) manufactured by Powerex Inc. It features a standard recovery type with a maximum off-state voltage of 1400 V and an on-state current rating of 175 A RMS. The device supports non-repetitive surge currents of 4000 A to 5500 A at 50/60 Hz. Key electrical parameters include a maximum gate trigger voltage of 3 V and a maximum gate trigger current of 150 mA. The on-state voltage drop is maximized at 1.8 V, while the maximum off-state leakage current is 25 mA. Operating temperature ranges from -40°C to 125°C.

Scrs Feature Summary

Scrs Procurement Notes

Verify the specific datasheet revision date when sourcing this component, as Powerex specifications may undergo updates. Confirm that the TO-209AB package dimensions match your chassis mounting requirements. Ensure that the gate trigger characteristics align with your driver circuit's output capabilities to guarantee reliable turn-on under all operating conditions.

Scrs Selection Notes

Select this part when a 1400 V blocking capability and 175 A continuous current are required in a stud-mount form factor. Compare the 1.8 V on-state voltage against alternative devices to assess conduction losses. Consider the 4000–5500 A surge rating for applications involving high inrush currents or fault conditions without requiring additional protection circuitry.

Scrs Part Context

This component belongs to the T600 series of phase control SCRs from Powerex, designed for medium to high-power industrial applications. The series offers various voltage and current ratings within the same physical package family, allowing for design flexibility. The T600141804BT specifically addresses the need for higher voltage blocking in 175 A class modules.

Scrs Replacement Considerations

Direct substitutes must match the 1400 V rating, 175 A current, and TO-209AB package. Verify equivalent gate trigger parameters and thermal resistance values. Cross-reference with other manufacturers' 1400 V stud-mount SCRs only if electrical and mechanical specifications are identical.
