NEW 2MBI100U4H-120 FUJI 2MBI100U4H120

Q1: What does each suffix code of 2MBI100U4H-120 mean?

A: 2=dual half-bridge, M=IGBT module, 100=100A rated current, U4=4th Gen U4 chip, H=standard package, 120=1200V VCES rating, all electrical & mechanical parameters of 2MBI100U4H-120 follow Fuji U4 series unified design standard.

Q2: What is the difference between 2MBI100U4H-120 and 2MBI100U4A-120?

A: Both share 1200V/100A electrical specs; only package outline and mounting hole spacing differ. The 2MBI100U4H-120 uses H standard base plate, more common for aftermarket replacement maintenance.

Q3: Can the NTC thermistor of 2MBI100U4H-120 be used for real-time overheat protection?

A: Yes, the built-in 5kΩ NTC on 2MBI100U4H-120 changes resistance linearly with temperature; MCU can read resistance value to judge substrate temperature and trigger current derating or shutdown protection.

Q4: What maximum switching frequency can 2MBI100U4H-120 stably run?

A: The rated stable switching frequency of the 2MBI100U4H-120 is 10kHz; under light load, it can support up to 20kHz without obvious temperature rise.

Q5: Can multiple 2MBI100U4H-120 modules be used in parallel for high-power inverters?

A: Yes, IGBT and FWD inside 2MBI100U4H-120 have positive temperature coefficient characteristics, which naturally balance current during parallel connection, suitable for multi-module high-power power cabinet design.
