HYBRID IC FOR DRIVING TRANSISTOR MODULES
DESCRIPTION
OUTLINE DRAWING
Dimensions in mm
M57951L is a Hybrid Integrated Circuit designed for driving Transis-
tor Modules QM30DY, QM50DY, etc., in an Inverter application. This
device operates as an isolation amplifier for Transistor Modules due
to the electrical isolation between the input and output, and includes
three independent circuits.
59MAX.
