Applications
The BUX81 is an epitaxial silicon NPN planar transistor that
has high current and high power handling capability and
high switching speed.
This device is especially suitable for switching–control
amplifiers, power gates, switching regulators, power-switch-
ing circuits converters, inverters and control circuits.Other
recommended applications include DC–RF amplifiers and
power oscillators.
