I am working on a home project that uses a micro controller to switch a set of transistors on and off rapidly(msecs). The current through the last transistor is about 300-400 mA to drive a high power LEDs. The Micro output pins produces ~25mA @ 5v. I currently use this to turn on/off a 3A capable NPN by connecting it to the base.
- I would like to switch over to using MOSFETs. Can someone help me understand the important symbols and their values on a MOSFET data sheet so that I can order the correct MOSFETs for my application. (First time user of MOSFETs)
- I am wondering about the gate/base resistor and how I determine that value also.
