Overview
The Powerex T707043344BY is a Silicon Controlled Rectifier (SCR) designed for high-power applications. It features a maximum repetitive peak reverse voltage of 400V and an on-state RMS current rating of 500A. The device utilizes a stud mount package with three terminals, specifically configured for high-current cable connections. Key electrical characteristics include a gate trigger current of 500mA and a circuit commutated turn-off time of 10µs. Operating within a temperature range of -40°C to +125°C, this single-element thyristor is built for robust industrial performance.
Feature Summary
- High current handling capability with 500A RMS on-state rating
- Fast switching performance with 10µs turn-off time
- Robust metal stud mount construction for efficient thermal management
- Wide operating temperature range suitable for harsh environments
Applications
- Industrial motor drives and control systems
- Power supply units requiring high current rectification
- Resistive load control in manufacturing equipment
- Inverter circuits and AC power regulation
Procurement Notes
Verify the specific datasheet version from Powerex Inc. to confirm exact pinout orientation and mounting torque specifications. Ensure that the procurement channel provides original manufacturer documentation to validate the RoHS compliance status and lot traceability. Cross-reference the part number against official distributor catalogs to avoid counterfeit components, as minor suffix variations may indicate different thermal or electrical grades.
Selection Notes
Select this component when a 400V blocking voltage and 500A continuous current capacity are required in a compact stud-mount form factor. Consider the 10µs turn-off time for applications demanding rapid commutation. Evaluate the thermal resistance of the mounting interface to ensure the junction temperature remains within the +125°C limit under full load conditions. Compare against similar T70 series devices if higher voltage ratings or different packaging options are needed.
Part Context
This SCR belongs to the Powerex T70 series, which is engineered for high-reliability power electronics. The series typically offers various voltage and current combinations to suit diverse industrial needs. As a standard recovery device, it is optimized for general-purpose rectification and switching tasks where robustness and predictable performance are critical. The T70 designation indicates the specific case style and mounting configuration used across multiple variants.
Replacement Considerations
Direct substitutes must match the 400V V(RRM), 500A I(T)RMS, and T70 stud mount package dimensions. Verify equivalent gate trigger currents and turn-off times to maintain circuit timing integrity. Consult Powerex's official cross-reference guides for approved alternative part numbers that share identical mechanical and electrical specifications.
