"WebIGBT turn−off. The typical clamp current is 1.1 A when the clamp voltage is 2.5 V; thus the IGBT gate voltage is clamped below the IGBT turn−on voltage. During IGBT turn−on, Vgcl drops, and this turns off the active Miller clamp switch and disables the active Miller clamp function. The Miller clamp function is only effective during IGBT " - Igbt protection
