Model ITC55300C performs ruggedness testing of power MOSFETs, discretes and modules and IGBTs, discretes and modules. It also tests single and dual diodes, and forward and reverse bias of IGBTs when used with an optional ITC55-RSF Output Selector Box.

The ITC55300C performs several types of tests that conform to MIL-STD-750C Method 3470. Method 3470 tests the capability of P- and N-Channel MOSFETs and IGBTs by stressing them to controlled energy levels. This is accomplished by the devices driving an unclamped inductive load.
