IGBT Modules

IGBT modules made by Littelfuse ensure highly efficient high-speed switching by combing metal-oxide–semiconductor field effect transistors (MOSFETs) with bipolar junction transistors (BJTs). The compact insulated gate bipolar transistor modules offer several design and performance benefits, including high reliability and lower costs for equipment manufacturers due to fewer components. We offer standard IGBT modules in many configurations, and we will work with you to custom design solutions. Common applications include EVs, solar inverters, uninterruptible power supplies, and welding machines.
