MOUNTING
The package bolts to part of the chassis or even the motor
assembly itself, depending on system requirements. in applica-
tions where this isn’t convenient, the hybrid can be mounted to
its own heatsink. The heat transfer in a hybrid is from semicon-
ductor junction to the bottom of the hybrid case. The flatness
and maximum temperature of this mounting surface are critical
to proper performance and reliability, because this is the only
method of dissipating the power created in the hybrid. Use a
mounting surface flatness of 0.004 inches/inch maximum. This
interface can be improved with the use of a thermal compound
or pad. The heatsink should be designed to insure that the case
temperature does not exceed +125°C.
