Extra Fast Recovery Diode Types F0240Y#250 to F0240Y#300

7.0 Computer Modelling Parameters

7.1 Device Dissipation Calculations

−V_{T 0}+ V_{T 0}+ 4 ff ² r W_AV

I_AV=

2 ff ² r

Where V_T0=2.271V, r_T= 2.853m

ff = form factor (normally unity for fast diode applications)

T

W_AV=

T = T_{j(MAX )}−T_K

7.2 Calculation of V_Fusing ABCD Coefficients

The forward characteristic I_FVs V_F, on page 6 is represented in two ways;

(i)

(ii)

the well established V_T0and r_Ttangent used for rating purposes and

a set of constants A, B, C, and D forming the coefficients of the representative equation for V_F

in terms of I_Fgiven below:

V_F= A + B  ln(I_F) + C  I_F+ D  I_F

The constants, derived by curve fitting Extra Fastware, are given in this report for both hot and cold

characteristics. The resulting values for V_Fagree with the true device characteristic over a current

range, which is limited to that plotted.

25°C Coefficients

-0.29682781

0.7249842

150°C Coefficients

1.135475814

0.04625971

1.79225×10^-3

5.65289×10^-4

8.0 Frequency Ratings

The curves illustrated in figures 8 to 16 are for guidance only and are superseded by the maximum

ratings shown on page 1.

9.0 Square wave ratings

These ratings are given for load component rate of rise of forward current of 100 and 500 A/µs.

10.0 Duty cycle lines

The 100% duty cycle is represented on all the ratings by a straight line. Other duties can be included

as parallel to the first.
