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.
Feature Summary
- Designed for high-power phase control applications requiring robust surge handling capabilities.
- Utilizes a chassis stud mount configuration for efficient thermal management and mechanical stability.
- Constructed as a standard recovery thyristor suitable for industrial power conversion systems.
Applications
- Industrial motor drives and variable frequency drive input stages
- High-power DC-to-AC inverter circuits
- Resistive and inductive load switching in heavy machinery
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.
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.
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.
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.
