Overview
The T700103004BY is a Silicon Controlled Rectifier (SCR) manufactured by Powerex Inc., designed for high-power industrial applications. It features a breakover voltage of 1000 V and supports a maximum breakover current ranging from 8400 A to 10000 A. The device operates with a gate trigger voltage of 3 V and handles a continuous RMS on-state current of 470 A, alongside an average on-state current rating of 300 A. Packaged in a TO-209 variation chassis mount configuration, it utilizes standard recovery technology suitable for robust power control environments.
Feature Summary
- High current handling capability with 470 A RMS and 300 A average ratings
- Robust voltage blocking performance at 1000 V breakover threshold
- Chassis and stud mount installation via TO-209 variation package
- Standard recovery characteristics optimized for phase control modulation
Applications
- Power supply systems requiring high-voltage isolation
- Industrial battery charger circuits
- Motor control drives and speed regulation
- Welding equipment power stages
- Electroplating rectifier modules
Procurement Notes
Verify the specific manufacturer datasheet for the T700 series to confirm exact thermal resistance values and mounting torque specifications required for reliable operation. Ensure that the selected heat sink interface matches the TO-209 variation package dimensions. Cross-reference the gate trigger parameters against the driving circuit capabilities to guarantee stable firing under all operating conditions.
Selection Notes
Select this component when designing circuits demanding high surge current tolerance and precise phase control modulation. The 1000 V rating provides adequate margin for standard industrial AC line voltages. Consider the 470 A RMS capacity for heavy-duty loads where thermal management is critical. Validate that the TO-209 chassis mount style aligns with the available mechanical space and cooling infrastructure in the target assembly.
Part Context
This SCR belongs to the T700 series from Powerex Inc., a lineup specialized for high-power thyristor applications. The series typically includes variants with different voltage and current ratings, all sharing similar rugged construction standards. These devices are engineered for durability in harsh electrical environments, offering consistent performance across a wide range of industrial power conversion tasks.
Replacement Considerations
Consult official Powerex documentation for direct cross-references within the T700 family. Verify that any substitute part maintains identical voltage, current, and package constraints to ensure system compatibility without redesign.
