VS-2N689

Scrs Overview

The VS-2N689 is a phase control thyristor (SCR) from the Vishay VS-2N681/VS-2N5205 series. It features a maximum repetitive peak reverse and off-state voltage of 500 V, with a non-repetitive peak reverse voltage of 600 V. The device supports a maximum RMS on-state current of 25 A and an average on-state current of 16 A at case temperatures between -65 °C and +65 °C. It utilizes a TO-48 (TO-208AA) stud mount package and operates within a junction temperature range of -65 °C to +125 °C.

Scrs Feature Summary

• General purpose stud mounted construction
• Broad forward and reverse voltage range through 1200 V
• Material categorization compliance

Scrs Applications

• Phase control circuits
• Industrial motor drives
• Power regulation systems

Scrs Procurement Notes

Verify the specific electrical ratings against the official Vishay datasheet document number 93706 before integration. Confirm that the thermal management design accommodates the specified junction-to-case thermal resistance and maximum allowable case temperature curves for the intended conduction angle. Ensure mounting torque specifications are strictly followed to maintain reliable electrical contact and thermal performance.

Scrs Selection Notes

Select this component when a 500 V rated SCR with a 25 A RMS capacity is required in a TO-48 package. Consider the -65 °C minimum operating temperature if deployment involves extreme cold environments. Evaluate the gate trigger characteristics against the available drive circuit capabilities to ensure reliable turn-on under all expected load conditions.

Scrs Part Context

This part belongs to the VS-2N681 and VS-2N5205 series of general purpose silicon controlled rectifiers manufactured by Vishay Semiconductors. The series offers a wide range of voltage ratings from 25 V to 1200 V, allowing designers to standardize on a single package style across various power levels while maintaining consistent mechanical and thermal interface requirements.

Scrs Replacement Considerations

Cross-reference with other manufacturers offering equivalent TO-48 packaged SCRs with matching 500 V blocking voltage and 25 A RMS current ratings. Verify that any substitute meets or exceeds the original dI/dt and dV/dt specifications to prevent device failure during switching events.
