VS-ST173S12PFP0

Scrs Overview

The VS-ST173S12PFP0 is a silicon controlled rectifier (SCR) manufactured by Vishay General Semiconductor. It features a standard recovery characteristic and is designed for chassis or stud mounting in the TO-209AB (TO-93) package. The device supports a repetitive peak forward blocking voltage of 1.2 kV and a non-repetitive surge current rating of up to 4680 A at 50 Hz or 4900 A at 60 Hz. It has an on-state voltage drop of approximately 2.07 V and a maximum off-state current of 40 mA.

Scrs Feature Summary

High surge current capability for robust transient handling
Standard recovery time for general industrial applications
Chassis or stud mount configuration for efficient thermal management

Scrs Applications

Industrial motor drives and control systems
High-power AC/DC conversion circuits
Resistive load switching applications

Scrs Procurement Notes

Verify the specific suffix PFP0 against official Vishay documentation to confirm pinout and mechanical dimensions. Ensure the TO-209AB package compatibility with your heatsink interface. Confirm RoHS compliance status if required by your manufacturing standards. Cross-reference the datasheet revision date to ensure parameter accuracy. Validate thermal resistance values for your specific mounting conditions.

Scrs Selection Notes

Select this component when high voltage blocking and significant surge current capacity are required in a stud-mount form factor. Consider the 2.07 V on-state voltage for power loss calculations in high-current scenarios. Evaluate the thermal performance requirements against the package's dissipation capabilities. Compare alternative SCRs with similar voltage ratings but different recovery speeds if fast switching is needed.

Scrs Part Context

This SCR belongs to Vishay's discrete thyristor portfolio, targeting high-power industrial electronics. The TO-209AB package allows for direct mounting to cooling structures, facilitating heat dissipation in demanding environments. It serves as a critical switching element in applications requiring reliable high-voltage isolation and robust fault tolerance.
