TIP42C Transistor Explained / Description:

TIP42C is a PNP general purpose transistor available in TO-220 package. This transistor is manufactured in four different types and their part numbers are TIP42, TIP42A, and TIP42B & TIP42C. The main differences between these parts are their voltage. TIP42C features highest load voltage from all. It can be used for any general purpose switching requirements. It can drive maximum load of -6A or -6000mA and maximum load voltage can be -100V.

Additionally it can also be used for any general amplification purposes. The maximum collector dissipation of the transistor is 65 watt due to which it can be used for high power audio amplification and also in audio amplifier stages.



Where We Can Use it & How to Use:

TIP42C can be used for variety of general purpose tasks in electronic circuits. With the max collector current of -6A it can drive high power switches, relays, transistors etc. Moreover with the max collector-emitter voltage of -100V one can also use it in designs that require high voltages under 100V. On the other hand it can be used in high power audio amplifiers to amplify audio upto 65W. This transistor can be used / wired same as any other BJT transistor.



Audio Amplifiers

Motor Driver Circuits

Battery Charger Designs

Power Supply Designs

Switching Loads under -6A

Darlington Pair


How to Safely Long Run in a Circuit:

For running TIP42C with safety and get long life performance in your circuits from this transistor it is essential to always use a suitable heatsink, use a suitable base resistor, do not drive load more than -6A and -100V. For safety always stay 20% below the maximum ratings and the storage and operating temperature should be between -65 to +150 Celsius.
