CoolGaN™ Transistor 100 V G3 in PQFN 3x3, 9.4 mΩ The IGB110S101 is a 100 V normally-off e-mode power transistor housed in a small PQFN 3x3 package, enabling high power density designs. Thanks to its low on-state resistance, it is the ideal choice for reliable performance in demanding high-voltage and high-current applications.
