Overview
The Powerex Inc. T700063504BY is a standard recovery Silicon Controlled Rectifier (SCR) designed for high-power industrial applications. It features a TO-209 variant package with stud mounting for efficient thermal dissipation. Key electrical parameters include a maximum repetitive peak off-state voltage of 400 V and a maximum average on-state current of 504 A. The device requires a maximum gate trigger voltage of 3 V and a maximum gate trigger current of 150 mA to initiate conduction.
Feature Summary
- High current handling capability suitable for heavy-duty power conversion
- Standard recovery characteristics optimized for general rectification tasks
- Robust stud-mount construction for secure mechanical attachment and heat sinking
Applications
- Industrial motor drives and variable frequency drives
- High-current DC power supplies and rectifiers
- Welding equipment power stages
Procurement Notes
Verify the specific suffix 'BY' against the manufacturer's official datasheet to confirm exact pinout, terminal configuration, and any minor manufacturing variations. Ensure the procurement channel provides authentic components from authorized distributors to avoid counterfeit devices that may lack specified electrical tolerances or reliability ratings.
Selection Notes
Select this component when an SCR with a 400 V blocking voltage and approximately 500 A continuous current rating is required. Consider the TO-209 stud package for compatibility with existing heatsink interfaces. Verify that the gate drive circuit can supply at least 150 mA at 3 V to ensure reliable triggering under all operating conditions.
Part Context
This part belongs to Powerex's lineup of high-power thyristors, typically utilized in medium-voltage and high-current industrial electronics. The TO-209 variant package is a legacy form factor often used in modular assemblies where direct mounting to cold plates or chassis is necessary for thermal management in high-power density designs.
Replacement Considerations
Consult official cross-reference guides for equivalent SCRs with matching 400 V / 500 A specifications and compatible TO-209 stud packages. Verify that any substitute maintains identical gate trigger requirements and thermal resistance characteristics to ensure system performance parity.
