VS-50RIA10

Scrs Overview

The VS-50RIA10 is a medium power phase control thyristor (SCR) from the Vishay VS-50RIA series, rated for a maximum repetitive peak off-state voltage of 100 V. It features a 50 A average on-state current and an 80 A RMS on-state current capability within a TO-65 (TO-208AC) stud mount package. The device supports junction temperatures from -40 °C to +125 °C and offers high surge capabilities with a non-repetitive peak surge current of 1430 A at 50 Hz. Triggering parameters include a maximum gate trigger current of 100 mA at 25 °C and a typical turn-off time of 110 μs.

Scrs Feature Summary

• High current rating with superior surge capabilities for robust operation
• Excellent dynamic characteristics including high dV/dt blocking
• Standard TO-65 stud base package for efficient thermal management

Scrs Applications

• Phase control applications in converters
• Lighting circuits
• Battery chargers
• Regulated power supplies
• Temperature and speed control circuits

Scrs Procurement Notes

Verify the specific voltage code suffix matches the required 100 V rating, as the VS-50RIA series spans multiple voltage options. Confirm thread type requirements; standard versions use 1/4"-28UNF-2A threads while metric variants utilize M6 x 1 threads. Ensure mounting torque specifications are adhered to for reliable thermal contact and mechanical stability during operation.

Scrs Selection Notes

Select this component for applications requiring a single SCR with a 100 V blocking voltage and 50 A continuous current handling. Consider the thermal resistance characteristics when designing heat sinks, noting the junction-to-case thermal resistance values provided for different conduction angles. Verify that the gate drive circuitry can supply the necessary trigger current and voltage levels across the specified operating temperature range.

Scrs Part Context

The VS-50RIA10 belongs to the VS-50RIA series of medium power phase control thyristors manufactured by Vishay Semiconductors. This series is designed for stud mounting and offers various voltage ratings up to 1200 V. The components are categorized for industrial power electronics applications where reliable phase control and high surge tolerance are essential.

Scrs Replacement Considerations

Direct substitutes within the same series include other voltage codes such as VS-50RIA20 or VS-50RIA40 if higher voltage ratings are acceptable. Metric thread versions like VS-50RIA10M provide equivalent electrical performance with different mounting hardware. Cross-brand replacements require matching IT(AV), VDRM, and package dimensions.
