Bend, Ore. - Four of Advanced Power Technology's CoolMOS power MOSFETs are now available in hermetic packages for use in military and aerospace applications and harsh environments. These 600- and 800-volt devices (APT11N80GC3, -17N80CC3, -20N60CC3, -47N60HC3), which deliver from 7.4 to 33.5 amps in TO-254, -257 and -258 packages, tout a specific on-resistance that's significantly lower than traditional MOSFETs, thus allowing for a smaller chip for a given total RDS(on). At the same time, they maintain the low gate-charge (lower drive requirements) and fast switching of conventional devices. These devices are available in production quantities. MIL-PRF-19500 screening is available. Volume pricing starts at $38.57.
