N-Channel PowerTrench^® MOSFET
30V, 121A, 4.7mΩ
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
r_DS(ON) and fast switching speed.
Applications
• DC/DC converters
Features
• r_DS(ON) = 4.7mΩ, V_GS = 10V, I_D = 40A
• r_DS(ON) = 6.0mΩ, V_GS = 4.5V, I_D = 40A
• High performance trench technology for extremely low
r_DS(ON)
• Low gate charge
• High power and current handling capability
