VS-80RIA80PBF

Scrs Overview

The VS-80RIA80PBF is a Silicon Controlled Rectifier (SCR) manufactured by Vishay Semiconductors. It features an 800 V rated repetitive off-state voltage and supports an average on-state current of 80 A. The device handles a non-repetitive peak on-state current of 1990 A. Key electrical parameters include a forward voltage of 1.6 V, a gate trigger voltage of 2.5 V, and a gate trigger current of 120 mA. It operates within a junction temperature range of -40°C to +125°C and utilizes a TO-94C (TO-209AC) threaded stud package.

Scrs Feature Summary

• High surge current capability with a non-repetitive peak on-state current rating of 1990 A for robust transient handling.
• Designed for high-voltage applications with an 800 V maximum repetitive off-state voltage rating.
• Utilizes a threaded stud mounting style in a TO-94C package for secure mechanical installation and thermal management.

Scrs Applications

• Industrial motor control systems
• Power supply circuits requiring high current switching
• Inverter and converter topologies

Scrs Procurement Notes

Verify component authenticity through authorized channels as the part status is listed as obsolete. Confirm RoHS compliance details via official datasheets before integration. Ensure storage conditions maintain integrity given the discontinued status. Validate pinout compatibility with existing PCB layouts or heatsink interfaces. Request batch-specific documentation to confirm manufacturing date codes and traceability requirements for critical assemblies.

Scrs Selection Notes

Select this component when designing circuits requiring an 80 A SCR with 800 V blocking capability. The TO-94C package necessitates specific mounting hardware and thermal interface materials. Verify that the gate trigger current of 120 mA aligns with the driving circuit's output capabilities. Consider the 1.6 V forward voltage drop for power loss calculations during conduction periods.

Scrs Part Context

This device belongs to the Vishay 80RIA series of thyristors. The series is characterized by high current density and rugged construction suitable for industrial power electronics. The TO-94C form factor provides a standardized footprint for stud-mounted applications, facilitating replacement in legacy designs requiring similar electrical specifications.

Scrs Replacement Considerations

Public confirmed substitute part numbers are not available in the provided source material due to the obsolete status. Engineers should consult Vishay technical support for qualified alternatives or evaluate equivalent offerings from other manufacturers based on matching electrical ratings and mechanical dimensions.
