ABSTRACT:
The invention relates to a MOSFET circuit having reduced output voltage oscillations, in which a smaller CoolMOS transistor (T2) with a zener diode (Z1) connected upstream of its gate is located in parallel with a larger CoolMOS transistor (T1), so that, during a switch-off operation, after the larger transistor has been switched off, the smaller transistor (T2) carries a tail current on account of the zener voltage still present, which tail current attenuates output oscillations of the voltage.
