Gate injection transistor
WebConsequently, GaN high electron mobility transistors (HEMTs) can operate at high switching frequencies without compromising efficiency. Infineon Technologies has two distinct GaN power device families: CoolGaN™ Schottky gate (SG) HEMTs and CoolGaN™ gate injection transistor (GIT) HEMTs. WebGallium nitride (GaN) transistors offer fundamental advantages over silicon. In particular, the higher critical electrical field makes it very attractive for power semiconductor devices with outstanding specific dynamic on-state resistance and smaller capacitances compared to silicon MOSFETs, which makes GaN HEMTs great for high speed switching applications.
