Scrs Procurement Notes

Verify the specific ordering suffix against official documentation to confirm physical attributes. The S90 designation indicates a special selection for a critical dV/dt rating of 1000 V/µs. The M suffix confirms the presence of metric M6 x 1 threads rather than standard imperial threads. Ensure the component meets the required industrial or consumer level specifications before procurement.

Scrs Selection Notes

Select this component for applications requiring robust thermal performance and high voltage blocking capabilities. The low thermal resistance facilitates efficient heat dissipation in stud-mounted configurations. Verify that the gate drive circuitry can supply the necessary trigger current across the full operating temperature range. Confirm compatibility with the specified conduction angles and surge current requirements.

Scrs Part Context

This part belongs to the VS-25RIA series of medium power phase control thyristors manufactured by Vishay Semiconductors. The series provides various voltage ratings up to 1200 V within the same mechanical footprint. These devices are designed for industrial and consumer level applications, offering improved reliability through enhanced glass passivation techniques.

Scrs Replacement Considerations

Consult the official datasheet for alternative part numbers within the VS-25RIA series that match specific voltage codes or thread requirements. Direct substitutes must maintain identical electrical ratings and mechanical dimensions to ensure proper integration without redesigning the mounting hardware.
