VS-25RIA20M

Scrs Overview

The VS-25RIA20M is a Silicon Controlled Rectifier (SCR) manufactured by Vishay General Semiconductor. It features a 200V repetitive peak off-state voltage and a 40A average on-state current rating. The device is housed in a TO-208AA (TO-48) stud mount package, designed for high-power applications requiring robust thermal management. Key electrical characteristics include a maximum gate trigger voltage of 2V and a maximum gate trigger current of 45mA. The component supports a non-repetitive surge current of 350A at 50/60Hz and operates within a junction temperature range of -40°C to 125°C.

Scrs Feature Summary

• High current handling capability with 40A average on-state rating
• Robust thermal design utilizing stud mount packaging
• Low gate trigger requirements for efficient control circuitry

Scrs Applications

• Industrial motor control systems
• AC power regulation circuits
• Battery charging equipment

Scrs Procurement Notes

Verify the specific ordering suffix 'M' confirms RoHS compliance and lead-free status as documented in official Vishay datasheets. Ensure the procurement channel provides valid traceability documentation matching the manufacturer's part number VS-25RIA20M. Confirm that the received components match the TO-208AA physical dimensions and pinout specifications to prevent integration errors in chassis-mounted assemblies.

Scrs Selection Notes

Select this component when a 200V blocking voltage and 40A continuous current capacity are required in a stud-mount configuration. Consider the TO-208AA package for superior heat dissipation compared to smaller surface-mount alternatives. Evaluate the 350A surge rating against potential inrush currents in the target application to ensure reliable operation under transient conditions without device failure.

Scrs Part Context

This SCR belongs to Vishay's general-purpose discrete semiconductor lineup, focusing on high-current power switching solutions. The TO-208AA package is standard for industrial-grade thyristors requiring direct mounting to heatsinks. It serves as a fundamental building block for phase-control and rectification applications where reliability under high thermal stress is critical.

Scrs Replacement Considerations

The VS-25RIA20 is listed as a parametric equivalent in distributor databases. Verify if the 'M' suffix denotes specific environmental compliance differences before substitution. Ensure any replacement maintains the identical TO-208AA mechanical footprint and electrical ratings to preserve system integrity.
