The BTA12-800CW with Thyristors - TRIACs TO-220AK RoHS manufactured by CJ is a three-terminal bidirectional device for controlling power in applications such as lamp dimming, motor control, heating control and power switching. It is constructed from a variety of semiconductor materials. It is housed in a TO-220AK RoHS package with standard pinout and compatible footprint. The device is a zero-crossing type thyristor with snubber (VDRM/VRRM Max of 800V). It has high surge current capability, low operating and thermal resistance, and is RoHS compliant. The BTA12-800CW can be used in both AC and DC control applications, and is well-suited for industrial, appliance, and consumer electronics applications.
