鈥?High Current Capability
Applications
The BUX39 is an epitaxial silicon NPN planar
transistor that has high current and high power han-
dling capability and high switching speed.
This device is especially suitable for switching鈥揷ontrol
amplifiers, power gates, switching regulators, power-
switching circuits converters, inverters and control cir-
cuits.Other recommended applications include
DC鈥揜F amplifiers and power oscillators.
