special-purpose test circuits . Testing Power MOSFETs on a curve tracer is a simple matter, provided the broad correspondence between bipolar transistor and Power MOSFET features are borne in mind. Table 1 matches some features of Power MOSFETs wi th their bipolar counterparts. The Power MOSFET used in all the examples is the IRF630.
