16TTS12

Overview

The Vishay 16TTS12 is a high-voltage phase control silicon controlled rectifier (SCR) from the 16TTS series, housed in a TO-220AB package. It features a maximum repetitive peak reverse voltage of 1200 V and an average on-state current rating of 10 A at a case temperature of 98 °C with 180° conduction. The device supports a non-repetitive surge current of up to 200 A under no voltage reapplied conditions. Key electrical characteristics include a maximum on-state voltage drop of 1.4 V at 10 A and 25 °C, a holding current of 100 mA, and a maximum gate trigger current of 60 mA at 25 °C. Operating junction temperatures range from -40 °C to 125 °C.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm lead-free status or other variations. Confirm that the requested component matches the exact 16TTS12 designation for 1200 V ratings. Ensure compatibility with industrial level qualification requirements specified in the datasheet before finalizing procurement decisions.

Selection Notes

Select this component for medium power phase control designs requiring 1200 V blocking capability. Evaluate thermal management needs based on the 1.3 °C/W junction-to-case thermal resistance. Consider the 10 A average current limit when designing for continuous sinusoidal waveforms. Verify gate drive parameters against the maximum DC gate trigger current specifications across the operating temperature range.
