High speed BJT recommendation

[hithesh123]

Can you guys recommend some parts numbers for high speed BJT switch.
Speed is 5MHz, Vcc = 30V, Ic = 100mA

Aply above requirements at that link :

I wanted to know some part numbers that are popular. So it's easy to get them from any local shop rather than digikey.

 

[andre_luis]

Depends of local market at each country.
Some brands are more common to find in Asia, Europe and US.

The 2N2222 works almost in the entire FW bandwidth. I suppouse that it is for analog aplication.

Can it swing 0-30V at 1MHz.

I simulated it the falling edge has higher slope than rising edge. I know this is bcoz of the stored base charge. Do you have any circuit/techniques to remove the base charge.

A Schottky diode from base to collector can help to minimise charge storage and speed up turn-off.

I don't think that 1MHz is considered high speed. I suppose that almost every general purpose BJT could reach frequencies above 1MHz.
Take a look at BC817. It is a cheap general purpose npn, that covers your specifications.
