Infineon FS35R12KE3G 1200V 35A IGBT Power Module

FS35R12KE3G 1200V 35A IGBT Power Module – EconoPACK 2B by Infineon

The FS35R12KE3G is a high-performance 1200V, 35A IGBT power module from Infineon Technologies, designed using advanced IGBT3 (E3 series) technology and packaged in the robust EconoPACK 2B housing. Engineered for use in 3-phase inverter applications, this module is widely recognized for its low conduction losses, high reliability, and excellent thermal performance under demanding operating conditions.

This module incorporates a 3-phase bridge topology, making it a preferred solution for industrial motor control, AC drives, uninterruptible power supplies (UPS), and servo systems. Its optimized switching behavior enables reduced switching losses and improved efficiency, while the integrated NTC thermistor allows accurate temperature monitoring for system-level protection. With a continuous collector current rating of 35A (and peak up to 55A), and a maximum collector-emitter voltage of 1200V, the FS35R12KE3G delivers the robust power handling required for medium-power applications.

Despite being officially obsolete, this IGBT module is still in demand within the secondary market for servicing legacy equipment, retrofits, and systems where direct compatibility is essential. Its rugged mechanical design and proven electrical characteristics continue to make it a dependable choice for engineers maintaining or upgrading existing installations.
