7MBR50VB-120-50 Visão geral
An IGBT (Insulated-Gate Bipolar Transistor) module is a power semiconductor switch that combines the high input impedance of a MOSFET gate with the low conduction loss of a bipolar output stage. A PIM (Power Integrated Module) additionally integrates the full 3-phase inverter, the input rectifier, and brake circuitry on one substrate, eliminating discrete assembly and reducing parasitic inductance. Within the broader taxonomy, IGBT modules sit below discrete IGBTs, above power MOSFETs in voltage/current handling, and serve as the building block of motor drive inverters, UPS systems, and servo amplifiers in the power electronics hierarchy.
Key specifications include a collector-emitter voltage (Vces) of 1200 V, continuous collector current (Ic) of 50 A at Tc=25°C, and a low Vce(sat) collector-emitter saturation voltage for reduced conduction loss. The integrated 3-phase bridge configuration is N-channel, and the built-in brake transistor simplifies dynamic braking implementation. Maximum gate-emitter voltage is ±20 V, and the module carries an RoHS-compliant M712 chassis-mount form factor compatible with PCB solder-pin mounting. The compact M712 EconoPIM footprint uses the industry-standard solder-pin pattern shared with M711, M719, and M720 PIM modules.
The V-series PIM is built on Fuji Electric's field-stop trench IGBT technology, paired with a soft-recovery rectifier on the input bridge. This generation targets reduced Vce(sat) for higher inverter efficiency at typical motor-drive switching frequencies of 4-15 kHz. Internal gate resistors are pre-trimmed to balance dv/dt, EMI, and switching loss, allowing the module to operate reliably with standard gate-drive optocouplers without external snubber networks in most applications.
Typical applications include general-purpose inverters for industrial motor control, AC and DC servo drive amplifiers, and uninterruptible power supplies. The integrated diode input bridge allows direct connection to a 3-phase AC mains or DC bus, while the integrated brake transistor supports rapid motor deceleration. The PIM's compact footprint suits 1-5 kW class inverters, HVAC compressors, and small industrial sewing or pump drives.
When designing with this module, observe the thermal resistance specification and ensure the heatsink surface is flat to within 50 µm with proper thermal compound. Use a low-inductance laminated bus for the DC link and tighten the module to the heatsink with the specified torque (typically 2.5-3.0 N·m for M712) to avoid thermal cycling stress on the substrate. Always include a gate soft-turn-off circuit if the application can produce short-circuit events above 10 µs.

Aplicações típicas
7MBR50VB-120-50 é adequado para 6 aplicaçãos: Industrial Motor Drive Inverter, AC Servo Drive Amplifier, Uninterruptible Power Supply (UPS), HVAC Compressor Drive, Solar Pump Inverter, Welding Inverter Power Stage.
Industrial Motor Drive Inverter
The 7MBR50VB-120-50 is designed for 1-5 kW 3-phase inverter output stages in industrial motor drives. The integrated 3-phase IGBT bridge, input rectifier, and brake transistor deliver a complete inverter building block on the M712 footprint, eliminating discrete IGBT/rectifier assembly and reducing parasitic inductance between switches. With a 1200V Vces rating it tolerates 480V AC mains (rectified to ~680V DC bus) with ample margin for regen transients; 50A Ic supports motor currents up to ~35A continuous after derating. The V-series low Vce(sat) reduces conduction loss by ~15% vs M-series predecessors, directly lowering heatsink size in the final drive chassis.
Recomendado
AC Servo Drive Amplifier
The 7MBR50VB-120-50 fits compact AC servo drive amplifiers controlling servomotors in CNC machines, robotics, and automated assembly. The 50A Ic delivers peak torque currents during transients, while the 1200V Vces rating supports 220/380V class servo amplifier DC buses. The integrated brake IGBT is critical for rapid servo deceleration to a stop, dissipating regenerative energy back to the brake resistor; field-stop trench IGBTs in the V-series sustain high switching frequencies (8-15 kHz) needed for current-loop bandwidth. The M712 EconoPIM footprint is the de-facto chassis-mount standard for servo amplifiers in the 1-3 kW class.
Recomendado
Uninterruptible Power Supply (UPS)
Within small-to-medium UPS systems rated 1-10 kVA, the 7MBR50VB-120-50 serves as the inverter switch block that converts DC battery voltage into 220V/380V AC output during mains failure. The 1200V Vces absorbs transfer surges when the static bypass switch transitions, and 50A continuous Ic supports 1-3 kVA single-phase or 3-5 kVA three-phase UPS chassis. The integrated converter allows simultaneous battery charging from the AC input while the inverter section is idle, maximizing PCB density. Low Vce(sat) reduces heat dissipation on the UPS heatsink and improves battery runtime during extended outages.
Recomendado
HVAC Compressor Drive
The 7MBR50VB-120-50 powers variable-frequency HVAC compressor drives controlling scroll and reciprocating compressors in commercial chillers and rooftop units. The integrated PIM topology saves PCB area for slimline compressor drive enclosures, and the 1200V Vces rating handles 480V three-phase commercial power cleanly. The brake IGBT is essential for regenerative braking during compressor deceleration, preventing DC bus overvoltage trips. The 50A Ic comfortably drives 3-5 HP compressor motors with thermal margin when heatsunk on the compressor inverter chassis.
Recomendado
Solar Pump Inverter
In solar pump inverters driving submersible pumps directly from photovoltaic arrays, the 7MBR50VB-120-50 operates from a variable DC bus (rather than rectified AC mains), making the integrated converter section a redundant path that may be left unused or repurposed. The 1200V Vces absorbs VOC transients from PV arrays, and the 50A Ic supports 3-7 HP irrigation pumps at MPPT operating points. The integrated brake transistor handles high pump deceleration energy during stop events, protecting the DC bus capacitor bank.
Recomendado
Welding Inverter Power Stage
Compact welding inverters in the 1-3 kW class use IGBT PIMs like the 7MBR50VB-120-50 for the high-frequency inverter stage that converts mains into low-voltage high-current welding output. The 1200V Vces handles welding arc strikes and 50A Ic delivers peak weld current pulses. The integrated brake/freewheel path supports inverter commutation under inductive welding load. The M712 EconoPIM footprint is commonly used in small MIG/TIG welders where size and weight matter more than higher-current discrete IGBT designs.

Notas de projeto
Mount the 7MBR50VB-120-50 to a flat heatsink with thermal interface material thickness 50-100 µm. Apply 1.0, 2.0, 3.0 N·m torque diagonally to the four M4 mounting screws in incremental stages, then verify baseplate flatness to within 50 µm. Junction-to-case Rth(j-c) is typically 0.55-0.75 K/W per switch; size the heatsink to keep Tj below 125°C in continuous motor-drive service.
Use a low-inductance laminated DC bus with metallized polypropylene snubber capacitors within 50 mm of the P and N pins. Place a 1 µF film capacitor and 0.1 µF ceramic bypass directly on the bus to absorb IGBT commutation spikes. Keep the gate-drive traces short (<50 mm) and twisted pair for gate/emitter to minimize dv/dt-induced Miller coupling.
Do not exceed ±20 V on the gate-emitter terminals - even transient overvoltages can rupture the SiO2 gate oxide. Apply +15 V on / -5 to -10 V off gate drive through an isolated gate-drive optocoupler. Always include desaturation detection with a 2-3 µs short-circuit reaction time to protect against shoot-through.
Route the high-side gate return paths (VGU, VGV, VGW) as separate Kelvin traces back to the corresponding emitter sense pins, not shared with power emitter returns. Use a guard ring of copper tied to the low-side emitter around the gate-drive circuit to decouple the gate driver from the noisy power loop. Keep the 24 solder pins straight during PCB insertion to avoid substrate stress.
Estimated: At 8 kHz switching with 600V DC bus, the 7MBR50VB-120-50 inverter emits common-mode EMI peaking at 1-15 MHz. Add a CM choke on the AC output side and an X2Y decoupling capacitor on the brake resistor terminal to meet EN 61800-3 C2/C3 limits. Keep gate-drive loop area below 1 cm² to minimize radiated ringing.
