2N687

Scrs Overview

The Central Semiconductor Corp 2N687 is a silicon controlled rectifier (SCR) designed for mains operation. It features a single configuration with a maximum repetitive peak reverse voltage of 300 V and an average on-state current of 25 A. The device utilizes a TO-48 case connection, typically configured for stud mounting, though through-hole variants are referenced in distributor listings. Key electrical parameters include a maximum DC gate trigger current of 40 mA. The component is RoHS compliant and currently active.

Scrs Feature Summary

• Designed specifically for mains operation applications
• High current handling capability with 25 A average on-state rating
• Robust voltage blocking up to 300 V repetitive peak reverse voltage

Scrs Applications

• Mains power control circuits
• Industrial thyristor switching applications
• High-current AC regulation systems

Scrs Procurement Notes

Verify the specific package variant when ordering, as sources reference both TO-48 stud mount and through-hole configurations for this part number. Confirm RoHS compliance status directly with the manufacturer or authorized distributors, as legacy data may vary. Ensure the application circuit supports the required gate trigger current of 40 mA maximum. Check for any recent product change notices regarding the TO-48 case style.

Scrs Selection Notes

Select the 2N687 for applications requiring high current capacity at moderate voltage levels. The 25 A rating suits heavy-duty AC loads. Consider thermal management requirements due to the power dissipation inherent in high-current SCR operation. The 300 V rating limits use to lower voltage mains or isolated secondary circuits. Compare against higher voltage SCRs if system transients exceed 300 V.

Scrs Part Context

The 2N687 belongs to the thyristor family from Central Semiconductor Corp, specifically within the SCR category. It is related to other series such as the 2N688 and 2N689, which offer higher voltage ratings. The component serves as a standard solution for robust power switching in industrial environments where reliable conduction and blocking are critical.
