R8 is only to turn off Q4 when it datasehet not being actively driven on. Looking for Germanium Transistor for Rovio. Since you haven’t specified speed, there is no way to say whether 5. You now say that you want to support a final load current of mA, and that the gain of Q4 is Here is the datasheet URL for this transistor.

For that you’d have to follow what is shown here and properly fill in all the assumptions like the beta of the transistors.

That shorts the base of Q1 to ground, turning it off.

First, let’s see how much current Daatasheet needs to sink when on. Note how the suggested by OP resistor values aren’t that well chosen. Anyone know where I can pick up one of these bad boys?

The LED D1 is used as an example of a load. Lower values turn it off faster. With R4 of 5. About Us Advertise Contact Us.

But then datashwet near the edge of what this PNP can do. Thanks for the feed back. Also from what I’ve read, Ge transistors are prone to eairly demise. Glade it worked for ya. Each transistor being on keeps the other on. For Q4 I think it depends on the load, how much current the load needs.

The circuits very likely will work but I would not say either circuit in the question is “well designed” or very “robust”. Sunday, 30 May Hey all, Datashert been trying to figure out why one of my Rovio’s motors only spins one way. Post as datzsheet guest Name.

This is a good answer and shows the process you need to follow to make proper component value choices.

I can’t find a relacement or equivilent. That turns off Q2, which then no longer provides base current to keep Q2 on. When SW1 is pressed for a little while, Q1 is turned on.

The RoboCommunity Webiste no longer accepts new users.

Let’s therefore work backwards requiring Q1 to sink 2.
