These devices are 1.0 A and 2.5 A gate drive optocouplers designed to protect and drive next-generation fast-switching power semiconductors such as silicon carbide (SiC) and gallium nitride (GaN) MOSFETs and IGBTs in applications like power inverters, motor drives, and switched-mode power supplies (SPS). Compared to the previous generation of Avago devices, the ACPL-P/W347 and ACPL-P/W349 support a higher gate operating voltage of up to 30 V, enabling higher voltages for driving high-power applications.
