s8550 transistor out put current - All About Circuits
Aug 19, 2021 · The current gain is not used when a transistor is a switch. Like most little transistors, the datasheet shows that it saturates when its base current is 1/10th its collector current.
Please tell me whether S8050 is similar to the 8050
Jul 14, 2010 · hi retched; thanks for replying ! bad transistor is 8550 and the ping arrangement is -E-C-B- , however the S8550 comes as -E-B-C-. so tell me is it ok to replace the bad one with the above one (S8550), after shifting the -B-C- pin position?

May 18, 2010 · can anyone pls give me a replacement transistor for SS8550....this transistor cant handle a higher voltage than 5V ...so i was hoping if i could find a...
Transistors-Please help - All About Circuits
May 3, 2013 · According to the Wing Shing data sheets, the S8050 and S8550 are rated for 500 mA collector current. (I assume the ML8050 and ML8550 are equivalents from a different manufacturer.) They are general purpose bipolar NPN and PNP transistors. A collector current rating higher than 500 mA would be a good idea, as well as a low Vce(sat) voltage.
