Note :
1.The data tested by surface mounted on a 1 inch2 FR-4 board with 2OZ copper,t<10sec.
2.The data tested by pulsed , pulse width 300us , duty cycle 2%
3.The EAS data shows Max. rating . The test condition is VDD=25V,VGS=10V,L=0.1mH,IAS=24A
4.The power dissipation is limited by 175junction temperature
5.The Min. value is 100% EAS tested guarantee.
6.The data is theoretically the same as ID and IDM , in real applications , should be limited by total power dissipation.
