Where We Can Use it & How to Use

2N2905 transistor is capable to work in any type of general purpose application that falls under its ratings. It features fast switching capabilities due to which it can be used for any type of fast and normal speed switching requirements and capable to drive load of upto 800mA. Moreover it can also be used as an amplifier not only in audio amplifier applications but it can also be used to amplify any type of electronic signals. Other than that it will also perform well in radio and RF circuits under 200MHz frequency.

Applications

• Radio & RF Applications
• Switching Loads under 800mA
• Audio Amplifier
• Signal Amplifier
• Darlington Pairs
• Many Types of General Purpose Applications

How to Get Long Term Performance in a Circuit

To get long term performance it is suggested to always use a component 20% below from its absolute maximum ratings and same applies to 2N2905 transistor. The max collector current is -800mA therefore do not drive load of more than -640mA. The max collector-emitter voltage is -40V therefore do not drive load of more than -32V. Use a proper heatsink with the transistor and always store or operate the transistor in temperature above -65 degree centigrade and below +200 degree centigrade.
