I have some big, 1.5A, 5-phase stepper motors and I need 10 transistors each to make a stepper driver for them. What kind of transistor do I need for a high-power switching application like this? And hopefully not too expensive.

Good transistors for making stepper motor driver

Well, I guess I have to figure out how to drive the damn thing first. There are only 5 wires...red, green, blue, black, and orange. I'm not sure if I need H-bridges or half-bridges or what.
