WebDIAC’s get damaged when voltage of wrong polarity is applied at its terminals. True False May be True or False Can't say. mechatronics Objective type Questions and Answers. ... TRIAC (Triode alternating current) is unipolar device. Gate loses control when the SCR starts conducting. How many terminals does a MOSFET have? WebAnswer: Both devices are multi layer semiconductors designed to operate in avalanche breakdown mode. This means the layers leak electrons and at a very stable voltage suddenly become conductive. The second and most important difference is that the TRIAC has a gate lead attached to parts of the in...
