4602-LV     3702-LV/L     9302-LV/L     Inductive Load Tester

Tesec has various types of Inductive Load tester that observes the shape of waves in the inductive load of MOSFET at the turn off and judges whether to pass within the Safety Operation Area (SOA) defined by V-Gate, IH and IL. In addition, the VDS value in the current value provided by IH can be measured.

New Tester 4602-LV;
There is a tendency that MOSFET has Low On Resistance so that it demands that Inductive Load Tester to have higher forcing current for measurement. The forcing current is limited by forcing voltage with previous test method. Thus it becomes difficult to test this kind of middle power range devices.
The 4602-LV has new test method (*VD-OFF mode & Time-Trip mode).
*VD-OFF mode : It is the mode to separate the VD power at Avalanche.
*Time-Trip mode : It turns off the devices after specified time from forcing current.  
Thus it can correpond with high current measurement. In addition, it is able to test wide range of devices by expanding the forcing voltage as 300V and forcing current as 200A.
