Componentes electrónica potência Diode Thyristor Transistor MOSFET GTO IGBT uncontrolled semi-controlled fully-controlled

Tecnologias de fabrico: 600, 1200, 1700 V (em off) turn-on 15V turn-off 0 - 7V A negative voltage bias is used to improve the IGBT immunity to collector-to-emitter dv/dt injected noise and reduce turn-off losses Tecnologias de fabrico: PUNCH-THROUGH (PT) better tradeoff between forward voltage drop and turn-off time NON-PUNCH-THROUGH (NPT) higher voltage capability (4kV) higher forward voltage drop more robust than PT

on-state power dissipation (not switching) switching

(w/ inductive load)

passive circuit elements have a tremendous influence on switching losses and operating areas
