www.st.comInductive parasitic turn-on can be also generated during turning off of the load current when a voltage is induced across the emitter stray inductance. In this condition, the decay of the current induces a voltage on source stray inductance that shifts the source potential to the negative level. The inductive parasitic turn-on, however, can be

fscdn.rohm.comwaveform of the surge voltage when LS turns off is shown in Figure 4. Figure 3 C Snubber Surge voltage is reduced by more than 50V (reaching 901V) and ringing frequency increases to 44.6MHz. It is because C SNB is placed close to the switches and as a result, the stray inductances (L SNB) involved in the switching path is reduced. In this case ...

For µA741: If the supply voltages are +15V and –15V the amplitude of the output voltage without clipping is 14V typically (guaranteed is 12V). The maximum that an Op Amp can supply to a load is restricted.
