Does anyone know where online i could buy transistors?? Im looking for a particular one that i can not seem to find any where in town. Its a 1 watt MPSW45A Darlington Transistor. BTW i NEED this part cuz im doing a simple project. Im building a one watt amplifier lol.
Those particular transistors were made by Motorola and are pretty rare nowadays. Also, since this was an OEM part packed in bulk for assembly companies, it is extremely hard to find anyone that will sell less than 1000 an order. Or maybe they have a $100 minimum order policy, etc. I think the original cost for each in bulk is like eight cents.
So, what you need to do is cross-reference this part and find a suitable replacement. Since I have a bit of time right now, I ran a cross-reference for you, and this is the part you need:
Yes, it is a direct replacment part. And I think you can buy just one at the link I posted above. I went all the way through checkout with just one, but shipping might be fierce. Better than having to buy 1000 of them though...
