2N689A

Scrs Overview

The Central Semiconductor Corp 2N689A is a Silicon Controlled Rectifier (SCR) designed for phase control applications. It features a maximum repetitive peak off-state voltage of 500 V and a continuous on-state current rating of 25 A. The device utilizes a stud mount configuration within a TO-48 package, supporting operation across a junction temperature range of -40°C to +125°C. Key electrical characteristics include a gate trigger voltage of 2 V, a gate trigger current of 40 mA, and a non-repetitive surge current capacity of 180 A.

Scrs Feature Summary

• Engineered specifically for high-current phase control applications requiring robust switching capabilities.
• Utilizes a stud mount construction to facilitate efficient thermal dissipation in power electronics environments.
• Provides reliable latching behavior with defined gate triggering thresholds for precise circuit control.

Scrs Applications

• Industrial motor speed control systems
• High-power lighting dimming circuits
• Solid-state relay implementations

Scrs Procurement Notes

Verify the specific suffix designation against official datasheets to confirm voltage and current ratings. Ensure compatibility with existing thermal management solutions due to the stud mount requirement. Confirm RoHS compliance status through manufacturer documentation prior to integration into regulated assemblies.

Scrs Selection Notes

Select this component when a 25 A SCR with a 500 V blocking capability is required. Evaluate the TO-48 package dimensions for mechanical fit. Consider the 180 A surge rating for inrush current handling. Verify that the gate drive circuit can supply the specified 40 mA trigger current reliably under all operating conditions.

Scrs Part Context

This part belongs to the standard Silicon Controlled Rectifier family from Central Semiconductor Corp. It shares functional similarities with other 25 A SCRs but is distinguished by its specific 500 V rating and TO-48 packaging. It serves as a discrete power switching element in thyristor-based circuits.

Scrs Replacement Considerations

Cross-reference with Vishay VS-2N689 for identical specifications. Verify pinout and mounting hole patterns match before substitution. Ensure thermal resistance characteristics are comparable for equivalent heat sink performance.
