16TTS08

Overview

The Vishay 16TTS08 is a phase control silicon controlled rectifier (SCR) in the High Voltage Series, housed in a TO-220AB package. It features glass passivation for reliable operation up to a junction temperature of 125 °C. Key electrical ratings include a maximum repetitive peak reverse voltage (VRRM) of 800 V and a maximum average on-state current (IT(AV)) of 10 A at 98 °C case temperature with half-sine wave conduction. The device supports a non-repetitive surge current (ITSM) of 200 A and has a typical on-state voltage drop (VT) of 1.4 V at 10 A. Triggering requires a maximum DC gate current of 60 mA at 25 °C.

Feature Summary

• Designed specifically for medium power switching and phase control applications
• Utilizes glass passivation technology for stable performance at elevated temperatures
• Qualified for industrial level environments
• Compatible with Vishay HPP input diodes, switches, and output rectifiers sharing identical package outlines

Applications

• Input rectification circuits featuring soft start functionality
• Single-phase bridge configurations
• Three-phase bridge configurations

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm lead-free status and production type. Ensure the selected part matches the required voltage rating, as the series includes variants with different breakdown voltages. Confirm that the TO-220AB package dimensions align with the thermal management design requirements for the intended application environment.

Selection Notes

Select this component based on its 800 V blocking capability and 10 A continuous current handling. Evaluate the thermal resistance characteristics to ensure adequate heat sinking for maintaining junction temperatures within the specified range. Consider the dV/dt and dI/dt ratings when designing snubber circuits or managing rapid transient conditions in the load path.

Part Context

This SCR belongs to the 16TTS.. High Voltage Series from Vishay High Power Products. The series is engineered for robust industrial use, offering standardized mounting options. The 16TTS08 variant specifically addresses applications requiring high voltage isolation combined with moderate current capacity, fitting into the broader portfolio of discrete semiconductor solutions for power conversion systems.

Replacement Considerations

The datasheet lists the 16TTS12 as a related part number within the same series, differing primarily in voltage rating rather than physical form factor. Verify pinout compatibility and thermal specifications before substituting.
