INTRODUCTION

 

Discuss the basic differences between JFETs and MOSFETs.

 

Why should MOSFETs be handles with special care?

 

EQUIPMENT

 

  • 1 power supply: 15V
  • 2 transistors: MTP10N05E/MC, IRF510
  • 1 resistor: 470Ω
  • 1 potentiometer 500kΩ
  • 1 diode: red LED
  • <List meters used>

 

PROCEDURE

 

Using Multisim construct the circuits shown below:

 

 

 

  1. Set the potentiometer to 0% then measure and record VGS,ID,VD.
  2. Set the value to 45% and take the three measurements.
  3. Increase the potentiometer until the LED turns off, record the readings.
  4. Replace the transistor with the IRF510 and repeat steps a) through c).

 

RESULTS

 

  MTP10N05E/MC IRF510
  VGS VD ID VGS VD ID
0%            
45%            
LED off            

 

Discuss the results.

 

What types of applications can this circuit be used in? Explain.
