Additional Details:

The 16TTS12 typically has a repetitive peak reverse voltage (VRRM) of 1200V and an average on-state current (IT(AV)) of around 16A. The gate trigger current (IGT) is relatively low, typically in the microampere range. It is commonly packaged in a TO-220 or similar package. Proper heat sinking is essential to maintain reliable operation at higher currents.
