Abstract :
A new MOS-bipolar power device in which forced-gate turn-off is achieved using a depletion region formed by an MOS gate structure is described. This device, called the depletion-mode thyristor (DMT), offers many highly desired features for high-voltage power switching applications: a) low ON-state drop, b) high input impedance, c) three-terminal operation, d) equivalent complementary devices, and e) high maximum controllable current. Experimental verification of device operation has been achieved using a UMOS gate technology.<>
