FR-4 board with 2OZ copper.
2.The data tested by pulsed , pulse width
≦
300us , duty cycle
≦
2%
3.The EAS data shows Max. rating . The test condition is V
DD
=25V,V
GS
=10V,L=0.1mH,I
AS
=25A
4.The power dissipation is limited by 150
℃
junction temperature
5.The data is theoretically the same as I
D
and I
DM
, in real applications , should be limited by total power dissipation.
