 When creating electronics projects, you might have wondered what the difference is between the two most used transistor types: bipolar junction transistors (BJT) and metal-oxide-semiconductor field-effect transistors (MOSFET). This guide will discuss some of the differences between a PNP bipolar transistor and a P-channel MOSFET, based on their characteristic curves. When creating electronics projects, you might have wondered what the difference is between the two most used transistor types: bipolar junction transistors (BJT) and metal-oxide-semiconductor field-effect transistors (MOSFET).

-First look at the behavior of the transistors when the collector-emitter, respectively the drain-source voltage is close to 0.+First look at the behavior of the transistors when the collector-emitter (or drain-source, depending on device) voltage is close to 0.
  
 The drain current of the MOSFET starts to rise shortly after the drain-source voltage rises above zero. The length of the linear region depends highly on the gate-source voltage: the higher the voltage, the later the current saturates. The slope of the curves is a moderate one, increasing with the gate-source voltage. The drain current of the MOSFET starts to rise shortly after the drain-source voltage rises above zero.
