High gain PNP Low power Transistor suggest - Electronic Circuits Projects Diagrams Free

Hi,

Originally, I am using CS9012 , PNP , EBC, low power, hfe =200, TO92.

Now I need a higher gain, can anyone suggest an equivalent to above but with higher gain , hfe >400?

Thank you,
Victor

A little darlington transistor has a gain of at least 10,000.
I have never used a PNP one.

A BC557C has a DC current gain of 420 to 800 at 2mA.
It has the European CBE pins layout so turn it around.
