What is Solid State Relay?
A solid state relay or an SSR is an electronic switching device which can be controlled by applying an external voltage to the control terminals.
The BT139 is a four-quadrant TRIAC from NXP that can handle medium power switching of loads up to 600V and 16A. With the ability to work in four quadrants, it can switch both positive and negative currents and operate with a positive or negative gate current.
STMicroelectronics’ new 800V 8H Triacs use the ST’s latest Snubberless high-temperature technology for achieving outstanding ruggedness in industrial, personal care, smart-home, and smar
