1. Describe the principle of working the semiconductor diode.

2. Give general information about considering diode: sketch and shapes of body, description of p-section and n-section, sign of voltage and current directions, function, operating conditions, storing conditions, materials and manufacturing techniques, table of qualification, performance, and maximum allowable parameters.

3. Using VAC equation for real diode , where – thermodynamic potential for room temperature, calculate parameters of and N by catalog characteristics(Бородин Б.А. « Справочник по полупроводниковым диодам»). Compare tables and graphics of calculated VAC for room temperature, after determination of absolute error and relative error :

;

, where I_calc and I_cat – calculational and nominal catalog value of current intensity for forward and reverse voltages.

4. Calculate and compare with catalog forward and reverse brunches of VAC for maximal and minimal temperatures. Make conclusions.

5. Calculate graphically (using catalog VAC`s for room temperature ) static resistances of the diode for forward nominal current ;

Calculate the coefficient of rectification for U_f≈U_r

Using VAC equation deduce formula for differential resistance of a diode for forward current

, Ohms.

Make a table and build graph of dependence r_dif(I_f).
