After a conversation with Mark (mcb1) about how I was always burning my fingers testing TO-220 devices, I decided to try to do something about it. The problem is I get excited when an idea comes to me so I take some short cuts and usually do not heat sink my TO-220 devices on the breadboard. Once in test mode, I worry that I am over heating them and then here comes the burning part. I grab them with my fingers and ouch. Today I gathered up some materials and set about building a couple of Do It ...
A few days ago I posed the question of whether I could add a second Darlington Power transistor in parallel to a commercial circuit that was poorly designed. The response from all of my mentors on E-14 was accurate and to the point. Amongst the many replies was one however that has caused me to take this question one step further and investigate an interesting component IC.   Don Hersey Wrote:   28.

There are three circumstances that have come together to inspire me to assemble this little test adapter circuit. First of all I like to and I am continually salvaging components from circuit boards. As many of these circuit boards come from equipment used in dental clinics there are a lot of components related to control of motors, solenoids, and other real world mechanical interfaces. I salvage a fair number of MOSFETs and as they are occasionally OEM or unmarked I have to always cobble a test ...
