TIP transistors are a series of bipolar junction power transistors originally introduced by Texas Instruments (standing for Texas Instruments Power.)

Available options:

TP41C - The TIP41C (often typed as TP41C) is a popular TIP41C Transistor which is a complementary NPN power transistor housed in a TO-220 plastic                 package.

TP42C - The TP42C (commonly known as the TIP42C) is a popular 100V, 6A PNP power bipolar junction transistor packaged in a TO-220 case. It is                         widely used for medium-power linear and switching applications like audio amplifiers and motor drivers.

TP31C - TP31C most commonly refers to the TIP31C, a popular NPN power transistor used in electronic amplifiers and switching circuits.

TP32C - TP32C can refer to several different products depending on the industry, most commonly an 8-inch Jade Glass Round Plaque award or a                         6-inch Rayon Glass Polishing Pad.
