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.

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.
Sign up using Email and Password. The load is a unspecified LED emitting visible light. Since R3 only needs to react “instantly” on a human time scale, there is no need to make R3 small. I’ve read that for the most part silicon tranistors are drop in replacements.
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.
