2017年9月23日 · The instructions call for installing two S8550 transistors, but the parts supplied are S8050 transistors. Looking at the specifications, these transistors have similar parameters except that the S8050 values are all negative. Are these two actually compatible?

2020年8月5日 · SS8550 is made by ON-semiconductor. It spec's at 1.5 A and 25 V S8550 is made by UTC (Unisonic). It spec's at 700 mA and 20 V

2022年5月13日 · This is the LED driver circuit from a thing I am trying to repair. I am attempting to draw a schematic. Q1 is marked S8050 and Q2 is marked S8550. I have checked this drawing multiple times because it didn't make sense. Checking the data I …

2021年8月19日 · 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.

2010年7月14日 · 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?

2010年5月18日 · 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...

2013年5月3日 · 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.

2022年4月8日 · Specification for DC supply Voltage = 5V DC Current = 20mA DC Specification for 5V Relay Trigger Voltage (Voltage across coil) = 5V DC Trigger Current (Nominal current) = 70mA I don't think I can activate realy with 5V, 20mA DC supply. I found that I need transistor to drive relay. I don't...

2016年10月14日 · I also check 2 transistor driver S8050 and S8550 are OK, diode N4148 is ok. I replace new IGBT and use one bulb 60w replace for fuse, turn on cooker but cooker not run, pls refer my video as link" To make sure problem is not solved I replace new fuse for bulb 60w and turn on cooker, and again fuse and IGBT shorted, cooker die again.

2011年3月7日 · Hi guys, I'm currently constructing a Colpitts oscillator based on NPN 2N2222. Here I use the NI MultiSIM 9.. It works perfectly, however, I get nothing when construct actual circuit (on breadboard) In the real circuit, the inductor is replaced by a coil inductor of 18SWG(1.25mm) diameter...
