Hi: The data sheet said the max collector current of BFU550W is 80mA. How do you define this value? Is it be measured in DC condition? Can it operate under 130mA collector current of 4% duty cycle?

This is the absolute maximum collector current that can safely flow in the transistor. If it is exceeded, the device is likely to destruct. The IC(MAX) rating should exceed the maximum value of collector current that can ever flow in the circuit.

>Can it operate under 130mA collector current of 4% duty cycle?

Transistor may survive this peak current if the pulse width is less than msec and average current is low. However, doing that is out of specs and shall be avoided.

My suggestion is to use a transistor with higher rated current like BFU590G or BFU590Q.
