VS-22RIA60

Scrs Overview

The VS-22RIA60 is a Silicon Controlled Rectifier (SCR) manufactured by Vishay Semiconductors, designed for high-power switching applications. It features a rated repetitive off-state voltage (VDRM) of 600 V and an on-state current capacity of 22 A. The device exhibits a forward voltage drop of 1.7 V at rated current and requires a gate trigger voltage of 2 V with a trigger current of 60 mA. It operates within a junction temperature range of -65°C to +125°C and utilizes a TO-48 stud mount package.

Scrs Feature Summary

• High surge current capability with a non-repetitive on-state peak current rating of 420 A
• Robust thermal performance supporting operation up to a maximum junction temperature of +125°C
• Stud mount construction in a TO-48 package for efficient heat dissipation and secure mechanical installation

Scrs Applications

• Industrial motor control systems requiring high current switching
• AC power control circuits and phase control applications
• Resistive load heating controllers

Scrs Procurement Notes

Verify the specific datasheet revision and product change notifications (PCN) prior to final design approval, as Vishay may update specifications or manufacturing locations. Confirm that the TO-48 mounting interface matches your thermal management design. Ensure compliance with RoHS directives if required by your assembly process. Cross-reference the manufacturer part number VS-22RIA60 with authorized distributors to confirm current availability and authenticity.

Scrs Selection Notes

Select this component when a 600 V blocking voltage and 22 A continuous current are required in a stud-mount configuration. Consider the 1.7 V forward voltage drop for thermal calculations and the 60 mA gate trigger current for driver circuit sizing. The TO-48 package dictates specific mounting torque and thermal interface requirements. Evaluate the 420 A surge rating against potential inrush currents in the target application to ensure device safety.

Scrs Part Context

This SCR belongs to Vishay's general-purpose thyristor lineup, specifically utilizing the TO-48 (TO-208AA) stud package format. This packaging style is standard for medium-to-high power discrete semiconductors requiring direct mounting to heatsinks. The device is categorized under Vishay's diode and rectifier division products, focusing on robust industrial-grade silicon technologies.

Scrs Replacement Considerations

Publicly confirmed substitute part numbers for the VS-22RIA60 were not identified in the provided documentation. Verify compatibility with alternative SCRs based on matching VDRM, IT(AV), package type, and electrical characteristics before substitution.
