Figure 2.

Internal parameters of the device

In order to better understand the impact of Rg on the device’s switching performance, two

different analyses are performed:

“Unclamped inductive switching” test on a characterization board; the device under test

is a 120 A / 40 V LL Vth device selected with different intrinsic Rg values.

Application analysis on a 2.5" HDD board, where “good” parts (with correct Rg value)

are compared with “bad” devices (with high Rg) in terms of switching behavior and

device temperature.
