TIP112 Transistor Explained / Description:

TIP110 is a TO-220 package dralington transistor designed for general purpose amplification and switching purposes. A darlinton transistor may look like a usual transistor from the outside or by its package but it totally is different from the inside or its internal circuit is totally different from usual transistors because it contains a pair of two transistors inside. These two internal transistors are wired in a special way to increase the gain of the transistor to a great extent. Therefore these transistors become ideal to use in applications that require high gain amplifications.

So the TIP110 also contains two transistors inside which can provide a gain of up to 1000. The other features of the transistor are a low collector-emitter saturation voltage of 2.5V, collector-emitter sustaining voltage of minimum 60V, and minimum lot-to-lot variations.

Looking at the absolute maximum ratings of the transistor the max collector-emitter voltage is 60V, max continuous collector current is 2A and max peak collector current is 4A (Peak collector current is the current rating the transistor can drive for only milliseconds and should not be confused with continuous collector current which is the actual load capacity of this transistor), max collector-base voltage is 60V, max emitter-base voltage is 5V, max base current is 50mA and max collector power dissipation is 50W.

The transistor can be used in a wide variety of commercial and industrial applications more on this can be found further in this article.

Where We Can Use it & How to Use:

TIP110 can be used in commercial and industrial circuits. It can be used in many automotive applications, audio related applications, power-related, controlling and driver circuits, etc. These are its broader applications and the detailed list of its applications can be found under the applications heading below.

For operating the transistor first, understand what voltage and current your application or load is required and make sure your load falls or use the 80% of your transistor’s absolute max limits because it is not ideal or good practice to use the transistor to its absolute maximum ratings so it is important to stay at least 20% below.

Now to achieve the desired collector current or output current you have to provide the required base current.

Make sure heat will be properly dissipated from the transistor for this purpose use a suitable heatsink with the transistor.

Moreover, if you are making an amplifier circuit first understand your circuit requirements then use the required passive components to get the required gain.

Applications:

Audio Amplifiers

Switching

Motor Drivers

Relay Drivers

LED Drivers

Battery Operated Applications

Voltage Regulator Circuits

Low Frequency Oscillators

Interface Circuits

How to Safely Long Run in a Circuit:

To safely operate the transistor first of all it is important to not operate it to its absolute maximum ratings and always stay 20% from these ratings. So the max output current of the transistor is 2A therefore the derived load should be not more than 1.6A. The maximum collector-emitter voltage is 60V so the load voltage should not be more than 48V. Use a proper heatsink with the transistor and always store or operate the transistor at temperatures above -65°C and below 150°C.
