The innovative WE-AGDT is a compact transformer in an EP7 package. It features a wide input voltage range from 9 to 36 V, a high saturation current of 4.5 A, as well as very low leakage inductance, and a very low capacitance of 6.8 pF between the windings. This gives rise to high common-mode transient immunity (CMTI) of the gate driver system.

This article reports the results obtained from an electrical characterization under high temperatures (25°C and 100°C), where forward voltage and reserve current were monitored for a set of 130 devices. The optimization process for these devices reflects an excellent behavior in on mode and a right compromise in a reverse way for the chosen application.
