AOD254 150V N-Channel MOSFET General Description The AOD254 uses trench MOSFET technology that is uniquely optimized to provide the most efficient high frequency switching performance.Power losses are minimized due to an extremely low combination of RDS(ON) and Crss.In addition,switching behavior is well controlled with a soft recovery body diode.This device is ideal for boost converters and synchronous rectifiers for consumer, telecom, industrial power supplies and LED backlighting. Features VDS ID (at VGS=10V) RDS(ON) (at VGS=10V) RDS(ON) (at VGS =4.5V) 150V 28A < 46mΩ < 53mΩ D G S C unless otherwise noted Absolute Maximum Ratings TA=25° Parameter Symbol Drain-Source Voltage VDS Gate-Source Voltage Continuous Drain Current Pulsed Drain Current C Continuous Drain Current Avalanc [ ... ]
