MD II and MD V: which is the lowest loss one?

A dynamic on bench comparison has been carried out on four different MD V/MD II

MOSFET couples in order to provide a reliable idea of their dynamic performances. All tests

have been issued by the same simple clamped inductive load test circuit (refer to Figure 7)

where the effects of parasitic elements have been reduced in order to make the effective

MOSFET behavior more understandable.

A 600 V,10 A SiC diode has been used as the clamp diode. The matches obtained under

evaluation are those displayed in Table 1. The following graphs show the energy ON, the

energy OFF, the di/dt, the dv/dt both at turn-on and turn-off of each compared match for

different RG values, and two ID current levels.
