Automotive small-signal
discretes solutions
Drive the future with our innovative portfolio
Automotive
Simplifying design through increased functionality
By delivering more functionality from individual products, we help to
cut development times. With just a few small-signal discretes several
circuit blocks can be build and therewith the number of different
components on the bill-of-materials can be reduced significantly.
Our small-signal discretes portfolio offers power and performance
levels previously only associated with much larger packages allowing
you to replace medium-power products with more compact
alternatives. And because you can now get high-performance
transistors and diodes in low-cost small-signal packages, you can
significantly cut costs. Whether it’s superior ESD protection or
loadswitch functionality integrated into a single component,
our portfolio makes it easier to design a new system.

small-signal discretes solutions
As automotive manufacturers strive to enhance safety, performance, comfort and
fuel-efficiency levels, the semiconductor content of vehicles is rising and electronic
systems are becoming more complex. Consequently, system suppliers must meet
increasingly severe requirements. Building on our expertise in both automotive
and small-signal discretes solutions, Philips offers an extensive portfolio of discrete
components that help suppliers meet the rigorous and diverse technical demands
on automotive electronics. The wide portfolio enables automotive designers to be
flexible in their designs. By means of integrated products the component count is
decreased and thus costs can be reduced.
All our new products are released in the well-known SOT23 package,
as well as in smaller packages like SOT323 (SC-70), SOD323 (SC-76)
and SOD323F (SC-90). To support the trend towards integration also
multiple transistors and diodes are available integrated into just a
single package like SOT457 (SC-74) and SOT363 (SC-88).
Philips has all the technologies in place to lead the way in small-signal
discretes products, allowing to develop automotive applications that
will drive the future.

Resistor-equipped transistors (RETs)
Developed especially for the automotive sector, 500 mA RETs combine a transistor
with two resistors to provide an optimal integrated solution for digital applications in
automotive systems, for example control units. Also an extensive portfolio with single
and double 100 mA RETs is available for standard small-signal digital applications.
Key features
- Transistor and two resistors integrated in
one package
- Initial 500 mA portfolio with several resistor
combinations in SOT23 and SOT346 (SC-59A)
- Further resistor combinations and double
versions are planned
Key benefits
- Lower handling and inventory costs
- Reduced boardspace requirements
- Shorter assembly times and reduced
pick-and-place efforts
- Simpler design process
- Increased end product reliability due to
fewer soldering points
