| Abstract |
A 450V 30A NPN transistor dedicated to DC contactor breaker is presented. At a forced gain of 10, it features a voltage drop of 0.5V at 30A. The turn off capability is 50A under 800V (Vcbo) by using a dedicated drive. A two layers metallisation has been developped in order to achieve this device. The structure has a fine emitter pitch. A fully brazed packaging is used to improve the surge behaviour and to decrease the stray inductance. |
