Bipolar transistors
Today’s portable devices demand
power switches that can operate
efficiently within limited power
supply headroom. The combination
of low saturation voltages, high
gain, and low voltage drive
characteristics that bipolars offer
makes them the natural choice for
operation at the 5V level and below.
Add their ruggedness and low
thermal resistance within minimal
footprints and it’s easy to see why
bipolars can also outperform
MOSFETs in higher voltage
applications that range from
automotive power converters to
telecomms interfaces.
Section 1.0
Zetex Semiconductors offers a
portfolio of bipolar products that builds
on successive generations of process
know-how, leading edge design and
innovation to manage voltages up to
500V with maximum efficiency.
Its latest range of products extends
the company’s leadership in building
ultra-low saturation voltage bipolar
transistors that permit ever smaller
surface mount packages to control
continuous currents of several amps.
Crucially, the specific die-area
resistance of these bipolar transistors
is significantly less than that of
competing MOSFETs, and is especially
suited to operation within cost
sensitive, power-conscious, and
space-constrained portable
applications. For a more in-depth
comparison of bipolar and MOSFET
technology read the article at the back
of the Discrete Component section of
this brochure.

Multichip devices that combine
transistors and Schottky diodes within
leadless QFN packages are also
available from Zetex to conserve
valuable space in high-density
assemblies. These devices especially
suit charger circuits, DC-DC
converters, MOSFET gate drivers, and
motor control applications in mobile
and portable equipment.
High voltage applications such as
backlight inverters, motor drivers,
and subscriber-line interface cards
also benefit from bipolar transistor
technology. Here too the bipolar’s
low saturation voltage challenges
MOSFETs in low to medium current
applications, and the availability of
surface mount packages that dissipate
up to 3W in SOT223 outline further
promotes overall design efficiency.
