Figure 14 and 15 show currents and voltages for the LCPx2-150B1 during both positive and

negative GR-1089 Core 10/1000 µs tests. These measurements were done at ±1 kV on a

board equipped with series resistance RS 50

Ω. For these measurements the positive gate

biased at + and - 65 V. In such a condition the maximum remaining voltage during the firing

phase is roughly ± 75 V.
