Product Overview
The Fuji Electric 2MBI600VX-120-50 is a 600 A / 1200 V dual IGBT power module from Fuji’s VX-series generation, housed in the industry-standard 62 mm footprint (approx. 106 × 62 × 30 mm, depending on heatsink interface) and built for high-current three-phase inverter legs where two IGBT elements + freewheel diodes are packaged together — most commonly wired as a half-bridge or as the upper+lower of a single phase leg in a 3-phase inverter stack. The “2MBI” decoder: 2 = 2-element (dual) module, MBI = MB-series IGBT (Fuji’s medium/high-power industrial line), 600 = 600 A collector current rating, VX = VX series (Fuji’s high-speed, low-VCE(sat) generation targeting 1200 V class for drives and inverters), 120 = 1200 V VCES, and -50 = lead/terminal/config variant (distinguishes this from the base 2MBI600VX-120 with different busbar or gate-lead layout). The Fuji 2MBI600VX-120-50 is therefore a drop-in 600 A / 1200 V workhorse for drive power sections, UPS inverters, renewable (PV/wind) grid-tie stages, and traction/converter auxiliaries that standardize on the 62 mm footprint.In ABB drive repair contexts — which is likely why this landed in your abb_ bucket — the Fuji 2MBI600VX-120-50 frequently appears on the BOM of ACS800, ACS880, and DCS800 power sections where ABB’s sourcing called up Fuji 600 A / 1200 V dual modules for the inverter bridge. Drive shops rebuilding a 400–500 kW ACS880-07 or a DCS800 DC drive’s armature bridge will often source Fuji 2MBI600VX-120-50 as the direct replacement when the original Fuji-sourced module needs swapping, provided the mechanical (62 mm), gate-emitter layout, and busbar spacing match. The VX series brings ~1.75–2.0 V typical VCE(sat) at rated current and sub-300 ns turn-off tail, which keeps switching loss and snubber stress manageable in 2–8 kHz PWM drive applications.Physically, the Fuji 2MBI600VX-120-50 is a slab-style module with AlSiC or Cu-baseplate, ceramic substrate (AlN or Al2O3), and screw-terminal or press-fit busbar pads for the main C/E terminals, with gate/emitter leads on the control side. It weighs roughly 0.34 kg, operates at -40 °C to +150 °C junction (Tvj op max typically +125/+150 °C depending on Fuji datasheet rev), and is designed for direct mounting to the drive’s heatsink with thermal grease and a centered clamping screw — the 62 mm mechanical standard that ABB, Siemens, Fuji, Mitsubishi, and Semikron all converge on, so spares logistics for drive shops stay sane.
