D44VM7

VERY HIGH SPEED NPN POWER TRANSISTORS COMPLEMENTARY TO THE D45VM SERIES D44VM Series 30- 80 VOLTS 8 AMP, 50 WATTS The D44VM is a NPN power transistor especially designed for use in switching circuits such as switching regulators, highfrequency inverters/converters and other applications where very fast switching and low-saturation voltages are n~cessary. This device is characterized with performance information which relates directly to switching, including 100° C maximum limits specified for switching times, saturation voltages, and leakage currents.
