To prevent the destruction of the device by avalanche due to high voltage drop over the power stage a voltage clamp mechanism ZDS(AZ) is implemented that limits negative output voltage to a certain level ( VS - VDS(AZ)). The clamping mechanism allows in addition a fast demagnetization of inductive loads because during the phase of active clamping the power is dissipated to a great extent rapidly inside the switch. On the other hand the power dissipated inside the switch while switching off inductive loads can cause considerable stress to the device. Therefore the maximum allowed energy at a given current (and by this also the inductance) is limited. In Figure 8 and Figure 9 the basic principle of active clamping as well as simplified waveforms when switching off inductive loads are illustrated.
