MITSUBISHI HYBRID ICs M57955L HYBRID IC FOR DRIVING HIGH BETA TRANSISTOR MODULES M57955L is a Hybrid Integrated Circuit designed for driving High Beta Transistor Modules QM50DY-HB, etc., in an Inverter application. This device operates as an isolation amplifier Transistor Modules due to the electrical isolation between the input and output circuits with a opto-coupler, as well as its driving capability which only requires single power supply.
