## **Notes:** 

-  Calculated continuous current based on maximum allowable junction temperature. Bond wire current limit is 90A by source bonding technology. Note that current limitations arising from heating of the device leads may occur with some lead mounting arrangements. (Refer to AN-1140) 

-  Repetitive rating; pulse width limited by max. junction temperature. 

- Limited by TJmax, starting TJ = 25°C, L = 72µH, RG = 50, IAS = 66A, VGS =10V. 

-  ISD  66A, di/dt  1190A/µs, VDD  V(BR)DSS, TJ 175°C. 

-  Pulse width  400µs; duty cycle  2%. 

- Coss eff. (TR) is a fixed capacitance that gives the same charging time as Coss while VDS is rising from 0 to 80% VDSS. 

- Coss eff. (ER) is a fixed capacitance that gives the same energy as Coss while VDS is rising from 0 to 80% VDSS. 

- R is measured at TJ approximately 90°C. 

- When mounted on 1" square PCB (FR-4 or G-10 Material). For recommended footprint and soldering techniques refer to 

- application note #AN-994.please refer to application note to AN-994:  http://www.irf.com/technical-info/appnotes/an-994.pdf  Limited by TJmax, starting TJ = 25°C, L = 1mH, RG = 50, IAS = 23A, VGS =10V. 

- Pulse drain current is limited at 360A by source bonding technology.

   - Purely a thermal phenomenon and failure occurs at a temperature far in excess of Tjmaxjmax. This is validated for every part type. 

2. Safe operation in Avalanche is allowed as long asTjmaxjmax is not exceeded. 

3. Equation below based on circuit and waveforms shown in Figures 23a, 23b. 

4. PD (ave) = Average power dissipation per single avalanche pulse. D (ave) = Average power dissipation per single avalanche pulse. = Average power dissipation per single avalanche pulse. 

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

7. T = Allowable rise in junction temperature, not to exceed TT = Allowable rise in junction temperature, not to exceed TT = Allowable rise in junction temperature, not to exceed Tjmax (assumed as 25°C in Figure 14, 15). 

   - ZthJC(D, tavthJC(D, tav(D, tavav) = Transient thermal resistance, see Figures 13) PD (ave) = 1/2 ( 1.3·BV·Iav) = T/ ZT/ ZthJC 

      - Iav = 2T/ [1.3·BV·Zth]
