

Calculated continuous current based on maximum allowable junction
temperature. Bond wire current limit is 195A. Note that current
limitations arising from heating of the device leads may occur with
some lead mounting arrangements.

Notes on Repetitive Avalanche Curves , Figures 14, 15:
(For further info, see AN-1005 at www.irf.com)
1. Avalanche failures assumption:

Purely a thermal phenomenon and failure occurs at a temperature far in
excess of T

jmax

. This is validated for every part type.

2. Safe operation in Avalanche is allowed as long asT

jmax

 is not exceeded.

3. Equation below based on circuit and waveforms shown in Figures 16a, 16b.
4. P

D (ave) 

= Average power dissipation per single avalanche pulse.

5. BV = Rated breakdown voltage (1.3 factor accounts for voltage increase

during avalanche).

6. I

av 

= Allowable avalanche current.
