200V N-Channel PowerTrench
MOSFET
General Description
This N-Channel MOSFET has been designed
specifically to improve the overall efficiency of DC/DC
converters using either synchronous or conventional
switching PWM controllers. It has been optimized for
low gate charge, low RDS(ON) and fast switching speed.
Applications
• DC/DC converter
Features
• 1.1 A, 200 V. RDS(ON) = 725 mΩ @ VGS = 10 V
• High performance trench technology for extremely
low RDS(ON)
• High power and current handling capability
• Fast switching speed
• Low gate charge (8nC typical)

Notes:
1.RθJA is the sum of the junction-to-case and case-to-ambient thermal resistance where the case thermal reference is defined as the solder mounting surface of
the drain pins. RθJC is guaranteed by design while RθCA is determined by the user's board design.
