2N686A

Scrs Overview

The Central Semiconductor Corp 2N686A is a silicon controlled rectifier (SCR) thyristor designed for high-power switching applications. It features a robust TO-48 metal package construction, providing superior thermal dissipation and mechanical stability compared to plastic alternatives. The device is rated for a continuous on-state current of 25 amperes, making it suitable for industrial loads. It supports off-state blocking voltages ranging from 25 volts up to 800 volts, allowing flexibility in circuit design across various voltage levels. This component serves as a reliable solution for phase control and power regulation tasks.

Scrs Feature Summary

• High current handling capability with a 25 ampere continuous on-state rating
• Durable TO-48 metal case construction for enhanced thermal management
• Wide voltage blocking range supporting diverse circuit requirements

Scrs Applications

• Industrial motor speed control systems
• High-power heating element regulation
• Phase control circuits for AC power management

Scrs Procurement Notes

Verify the specific voltage rating suffix required for your application, as the base part number covers a range up to 800V. Confirm that the TO-48 mounting style fits your chassis or heatsink constraints. Ensure the gate trigger characteristics align with your driving logic levels before finalizing the order.

Scrs Selection Notes

Select this component when high surge current capacity and ruggedness are prioritized over compact size. The TO-48 package offers better heat sinking than standard plastic packages but requires appropriate mounting hardware. Consider the specific voltage variant needed within the 25V to 800V range to match the peak inverse voltage of the load.

Scrs Part Context

This SCR belongs to the standard recovery thyristor family manufactured by Central Semiconductor. It is distinct from fast-recovery or reverse-conducting variants, focusing on general-purpose high-current switching. The TO-48 form factor places it in the category of hermetically sealed or ruggedized discrete power devices used in demanding environments.

Scrs Replacement Considerations

Cross-reference with other 25A TO-48 SCRs such as the 2N686 series equivalents. Verify pinout compatibility and thermal resistance values to ensure direct substitution without redesigning the cooling infrastructure.
