The BTB10-600BWRG with Triac is a Snubberless™ device manufactured by STMicroelectronics. It is a 600V, 10A, 50mA three-terminal junction non-isolated Thyristor in an TO220AB package. The device is a type of triac that offers robust load control with a maximum voltage of 600V and a current rating of up to 10A. It also has a low hold current of 50mA which allows it to turn off faster than conventional thyristors. This makes it suitable for use in high power applications including AC motor control, rectification, and switchmode power supply applications. Additionally, its Snubberless™ technology eliminates the need for a discrete snubber circuit, making it highly reliable and cost effective compared to other triac components.
