sl100 transistor

Greetings! Where can I buy sl100 transistor or its equivalent in the Philippines? My son needs this sl100 transistor to complete his mobile phone battery charger.

I don't know what a SL100 transistor is. Show the parameters you care about and there will likely be a common part that does what you need.

sir,
you can find this in alldatasheets.com or findchips.com. once please visit the website that might me helpful.

No. I'm not going to chase down a datasheet for something you should be supplying information for. That's your responsibility.

Besides, a datasheet will tell me all the parameters of a part, not which ones you care about. Finding a substitute that meets or exceeds all parameters could be difficult. However, no design relies on the outer values of all parameters. Finding a substitute that meets your needs is likely a lot easier.

I think that you have a typo in the part number. Where did you get that part number? Send a link or upload the schematic.

Olin:

I re-read the chain here and I think Praveen was advising the person that asked the question originally (Evelyn) to go to those sites to get the datasheets.

Still, your point is very well taken: without knowing what they care about, there is no way to really recommend "an equivalent".

Plus, as Cody M. points out in a subsequent post, I suspect there is a typo in the part number. Likely confused case markings with part number which are not always the same...

Oh, I see that now. I didn't notice there were two different people. It didn't help that he addressed his comment to "sir", instead of "olin" or "Evelyn".

In any case, we still need to know what parameters of the transistor are required for the circuit. Most likely there are many possible substitutes, but without parameters it's hard to know.

David,
you were right, i was addressing "evelyn", to visit the website. thank u for solving the issue.

Sir:

Follow-up to the transistor sl100. One of the reference of my son to his mobile phone project is http://www.electronicsforu.com/EFYLinux/circuit/mar2004/Cir-01-mobile-charger.pdf

Any replacement or alternate to sl100 transistor that can be bought in the Philippines to be used in his project will be greatly appreciated.

Thank you.

How about the CL100? that seems the same, but the best way is just go to electronic parts seller and ask if they have something similar, because i don't know what is availlable in the Phillipines

Just about any medium power NPN transistor will do there. This is not a demanding application. You want a package that can dissipate some heat, but it doesn't need to be excessive since the current it limited to 120mA. I keep TIP41 transistors around for such applications, but just about any NPN in a TO-220 package can do this job.

Ah, TIP41 BJTs. Ubiquitous, versatile, and made by a half-dozen or more semiconductor manufacturers so you can pretty much always find some.

I fondly remember using them in college Electronics labs not so long ago as simple transistor signal amplifiers. And once for what turned out to be a very not LDO linear regulator (Vce saturation spec not so awesome for that application).

Although it looks like the Pb free monster is getting its claws on them and the manufacturers are going to stop shipping the old ones and now only do ones with lead free caveats in the part number. Oh well, I guess I can at least use that as an excuse for my ugly solder jobs.
