    Is ONS the worth the mark up compared to ISC?

    Looking at MJ15024/25 TO-3 Transistors and ONS (Onsemi) cost three times more than the same ones from ISC (Inchange Semiconductor Company), are the they worth the extra? What have your experiences been? Shouldn't they be the same, if the specs are?

    OnSemi ThermalTrak power transistors

    OnSemi finally did what so many have suggested and put a matched bias diode junction in the same case as the output transistor. They call them ThermalTrak and is a 5-pin TO-264 case. No more bias lag issues. I will have to try these out. Datasheet attached.

    Matching TO 3 output transistors. MJ15022

    Hi, looking for some advice please. I'm replacing output transistors in a Rotel RA913 and need to match them. My cheap transistor tester displays the following for the four transistors: B =62 Uf = 554mV B =72 Uf = 548mV B =62 Uf = 555mV B =58 Uf = 556mV Which number(s) should I be best...
