Abstract
A bidirectional two-terminal ungated thyristor (9) having two wide-base portions (25, 27). The bidirectional two-terminal ungated thyristor (9) has a first semiconductor device having a first narrow-base portion (28) in series with a first wide-base portion (25), and a second semiconductor device having a second narrow-base portion (26) in series with a second wide-base portion (27). A width of the first wide base portion (25) and a width of the second wide base portion (27) are decreased to decrease a total base width. The first and second wide-base portions (25, 27) having a decreased width produce a low forward voltage drop across the bidirectional two-terminal ungated thyristor (9); thus, improving a power dissipation capability of the bidirectional two-terminal ungated thyristor (9).
