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

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Originally made by Texas Instruments - power darlington Ic max ~ 3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.

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).
