Infineon’s CoolGaN HEMTs Enable Efficient High-Speed Switching

by admin

Mouser Electronics, Inc., is now stocking the CoolGaN™ gallium nitride (GaN) HEMTs from Infineon Technologies. Featuring high efficiency and power density, the CoolGaN high-electron-mobility transistors (HEMTs) facilitate high-speed switching in semiconductor power supplies. Suitable for both hard- and soft-switching topologies, the CoolGan HEMTs are ideal for applications such as wireless charging, switched mode power supply (SMPS), telecommunications, hyperscale data centers, and servers.

The Infineon CoolGaN HEMTs, available from Mouser Electronics, offer exceptional quality when compared with silicon switching devices. The CoolGaN HEMTs offer 10 times’ lower output charge and gate charge compared to silicon transistors, as well as ten times’ higher breakdown field and double the mobility. Optimized for turn-on and turn-off, the devices feature new topologies and current modulation to deliver innovative switching solutions. The HEMTs’ surface-mount packaging ensures that switching capabilities are fully accessible, while the devices’ compact design enable their use in a variety of limited-space applications.

Infineon’s CoolGaN Gallium Nitride HEMTs are supported by the EVAL_1EDF_G1_HB_GAN and EVAL_2500W_PFC_G evaluation platforms. The EVAL_1EDF_G1_HB_GAN board features a CoolGaN 600 V HEMT and an Infineon GaN EiceDRIVER™ gate driver IC to enable engineers to evaluate high-frequency GaN capabilities in the universal half-bridge topology for converter and inverter applications. The EVAL_2500W_PFC_G board includes CoolGaN 600V e-mode HEMTs, a CoolMOS™ C7 Gold superjunction MOSFET, and EiceDRIVER gate driver ICs to deliver a 2.5 kW full-bridge power factor correction (PFC) evaluation tool that boosts system efficiency above 99 percent in energy-critical applications like SMPS and telecom rectifiers.
