Overview
The T700123004BY is a standard recovery Silicon Controlled Rectifier (SCR) manufactured by Powerex Inc. It utilizes a TO-209 variant package designed for base and stud mounting configurations. The device supports a maximum repetitive off-state voltage of 400 V and an average on-state current of 250 A. Key gate triggering specifications include a maximum gate trigger current of 150 mA and a maximum gate trigger voltage of 3 V.
Feature Summary
- Standard recovery type construction suitable for general power control applications
- Robust mechanical design enabling secure base or stud mounting installations
- High current carrying capability defined by a 250 A average on-state rating
Applications
- Industrial motor drive systems requiring high current switching
- AC power control circuits utilizing thyristor-based regulation
- Resistive load heating elements controlled via phase angle firing
Procurement Notes
Verify the specific suffix BY against official Powerex documentation to confirm exact pinout and thermal characteristics. Confirm that the TO-209 variant package matches your existing heatsink interface requirements. Ensure the 400 V voltage rating aligns with your circuit's peak inverse voltage demands before finalizing procurement orders.
Selection Notes
Select this component when a 250 A RMS current capacity is required within a compact TO-209 form factor. The 400 V blocking voltage makes it suitable for lower voltage industrial AC lines. Consider the standard recovery speed for non-high-frequency switching environments where cost-effective robustness is prioritized over ultra-fast switching performance.
Part Context
This SCR belongs to Powerex's lineup of high-power discrete semiconductor devices. The TO-209 variant package provides a standardized footprint for industrial mounting solutions. These components are engineered for durability in demanding electrical environments, offering reliable performance in heavy-duty power conversion and control tasks across various manufacturing sectors.
Replacement Considerations
Consult official cross-reference lists for direct equivalents. Verify that any substitute maintains identical 250 A current ratings and 400 V voltage limits. Ensure the replacement package matches the TO-209 variant dimensions for proper mechanical fitment.
