overview

Model ITC55100C is the latest generation of the industry standard series of ITC55100 testers. The system has been designed around a very powerful micro-controller that gives it a timing resolution of 40ns, twenty times faster than the previous model. Its response time to the peak and zero current is improved ten times. Combined this gives greater accuracy for the charging and avalanche times and for the reported peak drain current.

Model ITC55100C has a bipolar gate drive as a standarfeature. The user can set a total gate drive of

up to 30V and can select how much of the 30V is positive and how much of it is negative. This feature ensures that the device is held off during avalanche

as required for certain devices.

The ITC55100C performs several types of tests that conform to MIL-STD-750E 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.
