The BUX39 is in SEMELAB’s maintenance series
and is NOT recommended for new designs.
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–control
amplifiers, power gates, switching regulators, power-
switching circuits converters, inverters and control cir-
cuits.Other recommended applications include
DC–RF amplifiers and power oscillators.
