Infineon FS50R12KT3 IGBT Module – 1200 V Six-Pack Bridge (EconoPACK™ 2)
The FS50R12KT3 is a six-pack IGBT module housed in the efficient EconoPACK™ 2 format, built for high-density power switching. Rated at 1,200 V and 50 A continuous current, it offers a balanced blend of efficiency, durability, and thermal resilience—ideal for industrial and commercial power electronics.
This module integrates fast TRENCHSTOP™ IGBT3 transistors paired with high-efficiency emitter-controlled diodes for rapid switching and low energy loss. Featuring a built-in NTC thermistor, it enables active temperature monitoring, enhancing system safety and longevity.
With a thermal resistance (case-to-heatsink) of just 0.02 K/W, the FS50R12KT3 maintains low junction temperatures even under heavy load, bolstering durability. Its lean 19 nH stray inductance supports fast switching and reduced system noise. The module also features a copper baseplate with AI₂O₃ internal insulation, a 2.5 kVrms isolation rating, and complies with creepage and clearance safety standards.
Applications encompass three-phase motor inverters, UPS systems, industrial drive circuits, and heating control—particularly where compact packaging, thermal efficiency, and integrated safety features are critical.
