Overview
The TIP32C is a silicon Epitaxial-base PNP power transistor manufactured by STMicroelectronics, but it is also available from other manufacturers such as Harris Corporation under similar part numbers like TIP32C119. This transistor is packaged in a Jedec TO-220 plastic package and is intended for use in medium power linear and switching applications.
The TIP32C is known for its high collector current and current gain, making it suitable for power switching and large signal amplification. It has a complementary NPN type, the TIP31C, and is part of a family that includes other similar transistors like TIP120, TIP121, and TIP122 (NPN) and TIP125, TIP126, and TIP127 (PNP).
