WebMay 30, 2024 · They can conduct in both directions, but you have to take into account also the intrinsic diode. ... Channels can carry current in either direction because there is nothing in particular about the channel of a MOSFET that makes it uni-directional to current. MOSFETs generally have a 4-quadrant response to the applied drain-source voltage ... WebWhen the voltage is applied, it will not conduct unless the voltage does not exceed the break over voltage V BO or a gate pulse is applied. As we know that TRAIC can conduct for both polarities of applied voltage and it can be triggered by both polarities of gate voltage for either direction. Therefore, the TRAIC can operate in 4 modes.
