TRENCHSTOP™ 5 F5 Discrete IGBTs Infineon TRENCHSTOP™ 5 F5 Discrete IGBTs are optimized for switching >,60kHz to deliver optimum efficiency, bridging the gap between MOSFETs and IGBTs. The F5 series features significantly lower switching losses compared to currently leading solutions. Targeting topologies are boost stages, PFC (AC-DC) stages, and high voltage DC-DC topologies commonly found in applications like uninterruptible power supplies (UPS), inverter welding machines, and switch-mode power supplies. The 650V TRENCHSTOP 5 F5 IGBTs are targeted for low inductance designs in combination with SiC diodes to offer 1% higher efficiency compared to 650V TRENCHSTOP 5 H5 family.
