## **������** 

- 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. ������������������ 

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

- Limited by TJmax, starting TJ = 25°C, L = 0.069mH 

   - RG = 50 Ω , IAS = 100A, VGS =10V. 

- ISD ≤ 100A, di/dt ≤ 1166A/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. 

- �θ ������������������������������������� 

- Limited by TJmax starting TJ = 25°C, L= 1mH, RG = 50 Ω , IAS = 40A, VGS =10V.
