TRENCHSTOP™ 5 H5 (High Speed 5) IGBTs Infineon TRENCHSTOP™ 5 H5 (High Speed 5) IGBTs are high-speed and designed with ultimate efficiency for applications switching faster than 30kHz. The High Speed 5 IGBTs feature TRENCHSTOP™ 5 technology and are co-packed with a RAPID 1 fast and soft antiparallel diode. Infineon H5 IGBTs offer leading efficiency in hard switching and resonant topologies and are a plug-and-play replacement for previous generation IGBTs. Typical applications include UPS, welding converters, solar string inverters, and mid- to high-range switching frequency converters.
