Overview
The TIP32C, produced by onsemi, is a silicon Epitaxial-base PNP power transistor packaged in a Jedec TO-220 plastic package. This transistor is designed for medium power linear and switching applications. It is the complementary PNP type to the NPN TIP31C transistor. The TIP32C is capable of handling a maximum continuous collector current of 3A and a peak current of 5A, with a maximum collector-emitter voltage of 100V. Its high collector dissipation of 40W makes it suitable for audio amplifier stages and as a standalone amplifier for driving speakers.
