transisor sl100

[domz15]

does anyone knows a replacement for transistor sl100?

 

[mvs sarma]

if you are from India, it is sold in various names
CL100, HL100, Bel100N, a replacement can be thought as per your situation need?

 

[domz15]

i am from the philippines? hmm i need it for my cellphone battery charger project.

 

[mvs sarma]

you may use 2N3019. for small currents even 2N2222 should work. take note of the pinout details for the deviceswhile mounting, if you are already having PCB.

a bc548 will also work if your circuit needs less current (300ma), i think 300ma is enough for your circuit although it might take a few more time to fully recharge your battery,

Absolutely not!
The max current for a BC548 is only 100mA. A BC327 has a max current of 500mA and a 2N4401 has a max current of 600mA.
Please read the datasheet before making wrong statements.

but this datasheet shows the current is 500mA..Maybe a wrong datasheet?

Now that is truly odd: your datasheet (for the BC548/A/B/C) does indeed show a maximum Ic of 500mA.

But my Fairchild datasheet for the BC546/547/548/549/550 (a different one) shows a maximum of only 100mA. What's the deal here? Will the real BC548 please stand up?

hi cz,
My d/s agrees with yours at 100mA.
Interestingly, right click on the 'other' d/s and note the properties dates.!!!!
ALL today, I suspect someone is playing games.

The BC548 was invented by Philips and has a 100mA max current. The original BC108 was in a metal case and its max current was also 100mA as shown in my 1968 Philips Silicon Transistors databook.

I also agree that Ziddik is playing games with "copy and paste". Anybody can copy and paste the spec's for a 2N3055 power transistor (15A max current) onto the datasheet of a little BC548. But the date in the properties shows when it was done.

what? I did't copy n paste anything, i got that datasheet from net n i have no idea what you are talking about, what made u think that i copy n pasted it?

@audioguru

..this is where from i downloaded the schematic..check it before babbling..https://philohome.com/sensors/gp2d12/gp2d12-datasheets/bc548.pdf

 

[audioguru]

Ziddik,
You are correct. I am sorry I accused you of tampering with the PDF.

The properties does not show the date when the PDF was made, it shows the date it was downloaded and saved.
Maybe a kid at Philohome played with copy and paste.

Hi Ziddik,
I believe someone has made a fake copy of that pdf. [ checked your link]

its ok guru

hi agu,
Looking at the 'suspect' datasheet for the BC548, I noticed it referred the reader to look at the Fairchild PN100 data for more information.
Surprise is that the 'suspect' datasheet is the same for the PN100 ie Ic 500mA.
The Fairchild logo is a poor fuzzy black/white copy of the original.

https://www.fairchildsemi.com/pf/PN/PN100A.html

Checking with Fairchild link, states Ic 100mA for BC548

So two questions: who do you think made this ersatz datasheet, but more importantly, why? Why would someone create such a misleading document?

(Document properties show someone named "kastillo" as the author, with a create date of 10/29/98.)

 

[crutschow]

....[/b]? Why would someone create such a misleading document?....

Likely the same reason hackers try to break into your computer and foul it up. Some people get a perverse pleasure out of messing things up for others.

 

[alec_t]

Don't rely on document properties (dates etc); they can be faked.

thanks for your help guys. what do you think is the best transistor for my circuit? it is my first time to make a project like this. i am only a student.
