TIP31 Description

Short technical summary and product information.

The Bourns TIP31 is an NPN Silicon Power Transistor designed for complementary use with the TIP32 series. It is housed in a TO-220-3 package, suitable for through-hole mounting.

 

Key electrical specifications include a continuous collector current (IC) of 3A and a peak collector current (ICM) of 5A. The collector-emitter voltage (VCEO) is rated at 40V for the TIP31 variant, with higher voltage ratings available for TIP31A, TIP31B, and TIP31C. The device can dissipate up to 40W at 25°C case temperature.

 

Thermal characteristics include an operating junction temperature range of -65°C to +150°C and a storage temperature range of -65°C to +150°C. The transistor is designed for power switching applications.

 

This series is marked as obsolete and is not recommended for new designs. It is important to consider this status when planning for new projects or replacements.
