| spoil the transient clamping action of the circuit. A simple RC snubber can also be used, as shown in Figure 7. Note, however, that an RC snubber not only limits the peak voltage, it also slows down the just at the end of it, as does a voltage clamp. A snubber is therefore less efficient than a true OFF, even though the DC supply voltage for the drain circuit is well below the V DS rating of the clamping circuit is shown in Figure 6, depending on the voltage and current rating of the circuit www.datasheetarchive.com/files/international-rectifier/docs/wcd00009/wcd0097c.htm |
