    I am working on a PWM fan control circuit. I am having a trouble
    figuring out what PNP transistor I need. All I have to go on besides
    the symbol is:
    Q1 TIP126PNP DARLINGTON OR SIMLIAR

    any help or suggestions would be great.

    Thanks
     
  2. TIP126 is the part number. Googling on "TIP126" reveals several
    manufacturers' datasheets; Fairchild semiconductor shows the device is in
    full production for less than $1.

    Originally made by Texas Instruments - power darlington Ic max ~ 3
    Amps. the type number gave the max Vce. different parts were probably
    40 V, 60 V and 80 V.

  4. You might try a TIP126, which is a Darlington pair (2 transistors in one
    package, the first one acting as a preamplifier for the second).
