C2073 Transistor Explained / Description

C2073 is an NPN transistor available in TO-220 package. This transistor is mainly designed for vertical output circuitry and to use for power amplification purposes but rather than these uses it can also be used for wide variety of general purpose applications. It is capable to deliver fast switching speed due to which it can be used in circuits where high speed switching is important. Moreover it can be used for many type of different switching applications and can drive load of upto 1.5A and the load voltage can be upto 150V. The max DC current gain is 40 to 140 and the max collector dissipation is 25 Watt.

Where We Can Use it & How to Use

As mentioned above C2073 is mainly designed to use in high power audio amplifier circuitry and for vertical output circuitry but it can also be used in wide variety of other applications. The max output current of the transistor is 1.5A due to which it can drive many loads under 1.5A such as relays, high power LEDs, high power transistors and any other load that falls under its output current limit.

 

Applications

Power Audio Amplifier Circuitry

Switching Loads under 1.5A

Vertical Output Circuitry

Darlington Pair

Many general purpose applications

 

How to Get Long Term Performance in a Circuit

To let this device serve you for years it is suggested to not use it on its absolute maximum ratings and always use it 20% below from its max ratings. The maximum collector current of the transistor is 1.5A therefore do not drive load of more than 1.2A, the max load voltage is 150V therefore do not drive load of more than 120V. Not using a suitable heatsink also shorten the life of the transistor therefore always use a proper heatsink. The storage and operating temperature is also an important point to consider thus always use it in temperature above -55 degree centigrade and below +150 degree centigrade.
