BJT application expansion by insertion of superjunction

International audienceIn this paper, some high voltage Bipolar Junction Transistors are presented and compared in order to suggest a switch for household appliances with fully turn-on, turn-off control. For the first time, a comparative theoretical study, using 2D simulations, shows that concepts like the "superjunction" improve the static behaviour of conventional BJT. These new structures are compared with a SJMOSFET and an IGBT. The new BJT exhibits lower static losses than SJMOSFET and gives up an interest in bipolar structure

BJT static behavior improvement by modification of the epitaxial layer

International audienceIn this paper, high voltage Bipolar Junction Transistors are presented and compared in order to suggest a bidirectional switch for household appliances with fully turn-on, turn-off control. A comparative theoretical study, using 2D simulations, shows that concepts like "superjunctions" and "floating islands" improve the static current gain without unwanted behavior like parasitic diodes
