VS-16RIA120MS90

Scrs Overview

The VS-16RIA120MS90 is a medium power phase control thyristor from the Vishay VS-16RIA series, rated for a maximum repetitive peak off-state voltage of 1200 V. It features an average on-state current of 16 A and an RMS on-state current of 35 A at a case temperature of 85 °C. The device utilizes a TO-48 (TO-208AA) package with an M6 x 1 metric thread stud base. It includes improved glass passivation for high reliability and exceptional stability at elevated temperatures.

Scrs Feature Summary

• Features improved glass passivation to ensure high reliability and exceptional stability at high temperatures.
• Provides high dI/dt and dV/dt capabilities for robust performance in demanding switching environments.
• Includes a special selection option offering a critical rate of rise of off-state voltage (dV/dt) of 1000 V/µs.

Scrs Applications

• Medium power switching applications
• Phase control circuits

Scrs Procurement Notes

Verify that the specific ordering suffix matches the required mechanical and electrical specifications. Confirm the 'M' designation indicates the M6 x 1 metric thread stud base rather than the standard imperial thread. Ensure the 'S90' suffix is present to verify the enhanced 1000 V/µs dV/dt rating. Cross-reference the voltage code '120' against the manufacturer's official voltage ratings table to confirm the 1200 V blocking capability.

Scrs Selection Notes

Select this component when a 1200 V blocking capability is required alongside a 16 A average current rating. The M6 x 1 metric thread stud base is necessary for compatibility with specific mounting hardware. The S90 suffix must be included if the application demands a critical dV/dt rating of 1000 V/µs instead of the standard 300 V/µs. Verify thermal management requirements based on the specified junction-to-case thermal resistance.

Scrs FAQ

What does the 'S90' suffix indicate in the part number?

The 'S90' suffix indicates a special selection where the device has a critical rate of rise of off-state voltage (dV/dt) of 1000 V/µs, compared to the standard value of 300 V/µs.

What type of mounting thread does the 'M' suffix specify?

The 'M' suffix specifies a metric thread stud base with dimensions M6 x 1, as opposed to the standard 1/4"-28UNF-2A imperial thread found in non-metric versions.

How is the maximum repetitive peak off-state voltage determined?

The voltage is determined by the third digit in the part number sequence multiplied by 10; for example, '120' corresponds to a maximum VDRM/VRRM of 1200 V.
