TN2540-600G-TR

Scrs Overview

The TN2540-600G-TR is a standard 25 A silicon controlled rectifier (SCR) manufactured by STMicroelectronics. It features a repetitive peak off-state voltage of 600 V and utilizes clip assembly technology to deliver superior surge current capabilities. The device is housed in an insulated TO-220AB package, providing an insulating voltage of 2500 V rms. It requires a triggering gate current of 40 mA for operation and holds UL1557 certification.

Scrs Feature Summary

• Utilizes clip assembly technology for enhanced surge current performance
• Insulated TO-220AB package with 2500 V rms isolation
• UL1557 certified for safety compliance

Scrs Applications

• General purpose AC switching applications
• AC-DC power supply front-end circuits
• Inrush current limitation systems

Scrs Procurement Notes

Verify the specific suffix 'G-TR' against official STMicroelectronics documentation to confirm tape-and-reel packaging and lead-free composition. Ensure the 600 V voltage rating matches the system requirements, as this part number variant differs from other voltage ratings within the TN2540 series. Cross-reference the UL file reference E81734 for regulatory compliance verification.

Scrs Selection Notes

Select this component when a robust 25 A SCR with high surge tolerance is required for general-purpose AC control. The insulated package simplifies heatsinking and mounting without additional electrical isolation components. Consider the 600 V blocking capability relative to the line voltage and transient spikes present in the target application environment.

Scrs Part Context

The TN2540 series represents STMicroelectronics' standard range of high-current SCRs designed for industrial and consumer power applications. These devices are engineered for reliability in demanding environments, leveraging advanced manufacturing techniques to ensure consistent performance across varying thermal conditions and electrical loads.

Scrs Replacement Considerations

Consult official STMicroelectronics substitution guides for verified equivalents. Generic replacements must match the 25 A current rating, 600 V blocking voltage, and TO-220AB insulated package form factor to maintain circuit integrity.
