No, however they will require more heat sinking than a Mosfet of equivalent current capacity. Since it is a switch (PWM) the LOW RDSon of most all power mosfets < .1 Ohm Vs a VCEsat of > 1Volt makes it a kinda No Brainer unless all you have are some tip121's? I don't remember which... But @5V gate voltage an IRF 540 is hard to beat for a GP Power Mosfet.
