2017年5月15日 · A BC107 was an old ordinary little transistor in a metal case. Its max Vceo is 45V, its max current is only 100mA and its hFE is from 125 to 500 at 2mA. A BC547 has the …

2021年10月25日 · Good morning all. Wonder if anyone could help in advising 2 equivalent transistors to replace a NPN BC107A package type TO-18 and PNP BC327B package type …

2011年7月30日 · Philips invented the BC107 in a metal case then made the BC547 in a plastic case. Fairchild simply copies it. The max emitter-base voltage is 7V because it is a reverse …

2013年5月20日 · I know these all transistors has different hFE: 547 547A 547B 547C And this different hFE may affect the bias on critical circuitry. I have few transistors but can't read its …

2013年10月4日 · Unfortunately I think I blew the temp control circuit, thinking it was just 2 wires to the heater I bunged 60 v up it, but its made from bc107's and a bfy51 so shouldnt be hard to …

2022年7月9日 · I know there is a great deal of poor schematics available but I have been doing a good deal of research before i settled on this one to build from. So I found a 12 year old article …

2009年10月20日 · It also depends on how much specific this transistor is to your circuit requirement.BC148 is used for small signal general purpose amplification.There are a lot with …

2005年9月14日 · hi, all i am trying to find some S8050 D-317 transisors or an alternative these are the only markings available i have been looking for a while now with no luck, :( any help you …

2016年7月7日 · Hello I am thinking of building the below circuit but i am short on components. I have all the others except SL100 transistor and BT44 triac which i can't seem to find in any …
