I have studied the datasheet of an NPN transistor, in datasheet MAX-POWER OF transistor is mention as 400 mW.

What is the meaning of max power?

Can it be generated by itself or do I have to give 400 mW to the transistor??

Thank you

I think this link can be helpful to you. There it is explained that the maximum power of a transistor is the total power that it can dissipate, so in your case, your NPN transistor is able to dissipate 400mW when it is activated.

Hope that helps!

  • \$\begingroup\$ Lead length affects the heat removal. Some people attach small heat sinks atop the transistor's case, and let airflow provide more cooling. \$\endgroup\$ Commented Oct 31, 2018 at 16:37
