VS-ST110S14P0PBF

Scrs Overview

The VS-ST110S14P0PBF is a Silicon Controlled Rectifier (SCR) manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum repetitive peak reverse voltage of 1.4 kV and a non-repetitive peak forward current rating of 175 A. The device utilizes a TO-209AC (TO-94) chassis package for stud mounting. It operates within a junction temperature range of -55°C to +125°C. The component is RoHS compliant and designed for high-power phase control applications requiring robust thermal management and high voltage blocking capabilities.

Scrs Feature Summary

• High voltage blocking capability with 1.4 kV repetitive peak reverse voltage rating
• Robust surge handling with 175 A non-repetitive peak forward current capacity
• Chassis mount construction in TO-209AC package for efficient heat dissipation
• Designed for phase control applications in industrial power systems

Scrs Applications

• Industrial motor drives and variable speed controls
• High-power AC voltage regulators and soft starters
• Resistive load switching in industrial heating systems
• Phase control circuits for large-scale power conversion

Scrs Procurement Notes

Verify the specific suffix PBF indicates RoHS compliance status against the latest manufacturer datasheet, as suffixes can denote packaging or environmental compliance variations. Confirm the TO-209AC mechanical dimensions match your mounting hardware specifications. Ensure thermal interface materials are compatible with the chassis mount design for optimal heat transfer. Validate that the 1.4 kV rating meets the peak inverse voltage requirements of your circuit topology under all operating conditions.

Scrs Selection Notes

Select this component when high voltage isolation and significant surge current handling are required in a single-phase or bridge configuration. The TO-209AC package is suitable for applications where direct chassis mounting provides necessary thermal relief. Consider the 175 A surge rating relative to the expected inrush currents in your load. Ensure the gate trigger characteristics align with your control circuitry drive capabilities for reliable turn-on performance.

Scrs Part Context

This SCR belongs to the VS-ST110 series from Vishay, designed for high-power industrial applications. The series typically includes variants with different voltage ratings such as 600 V, 800 V, and 1.2 kV options. The TO-209AC form factor is standard for medium-to-high power thyristors requiring stud mounting. This specific model represents the 1.4 kV variant within the lineup, offering higher voltage blocking than standard 1.2 kV counterparts.

Scrs Replacement Considerations

Direct replacements must match the 1.4 kV voltage rating, 175 A surge current, and TO-209AC package. Verify gate trigger parameters and on-state voltage drop similarities. Cross-reference with other manufacturers' 1.4 kV SCRs in TO-209AC packages, ensuring mechanical pinout compatibility. Check if alternative suffixes indicate different thermal or electrical tolerances.
