TIP32 is listed in the Single Bipolar Transistors range at ChipApex. The manufacturer field lists Fairchild Semiconductor. Its product description is TRANS PNP 40V 3A TO-220-3. Review the specifications below when checking this part for your BOM.
The Fairchild Semiconductor TIP32 is a PNP epitaxial silicon power transistor designed for general-purpose switching and amplification applications. It features a maximum collector current of 3 A and a collector-emitter voltage rating of 80 V. The device is housed in a TO-220AB flange mount package with three pins, utilizing plastic/epoxy encapsulation. It operates within a standard temperature range and supports through-hole mounting for robust thermal dissipation.
Verify the manufacturer origin carefully, as the TIP32 part number is widely produced by multiple vendors including STMicroelectronics, ON Semiconductor, and Rochester Electronics. Confirm the specific datasheet version matches your design requirements, particularly regarding pinout consistency and thermal resistance values across different production batches.
Select this component when a PNP counterpart to NPN power transistors like the TIP31 is required. Ensure the application voltage does not exceed the 80 V collector-emitter limit. Consider the TO-220 package size for adequate heat sinking in high-current scenarios where thermal management is critical for sustained operation.
This component belongs to the popular TIP3x series of power transistors, which are industry-standard replacements for older discrete power devices. The series includes complementary NPN (TIP31) and PNP (TIP32) variants, widely used in educational kits and legacy industrial equipment due to their availability and standardized pinouts.
