The TIP41C is a base island technology NPN
power transistor in TO-220 plastic package that
make this device suitable for audio, power linear
and switching applications. The complementary
PNP type is TIP42C
Note:For PNP types voltage and current values are negative

3 Package mechanical data
In order to meet environmental requirements, ST offers these devices in ECOPACK®
packages. These packages have a Lead-free second level interconnect . The category of
second level interconnect is marked on the package and on the inner box label, in
compliance with JEDEC Standard JESD97. The maximum ratings related to soldering
conditions are also marked on the inner box label. ECOPACK is an ST trademark.
ECOPACK specifications are available at: www.st.com
