APT5010JFLL 500V 44A S G D 0.100W S POWER MOS 7TM FREDFET Power MOS 7TM is a new generation of low loss, high voltage, N-Channel enhancement mode power MOSFETS. Both conduction and switching losses are addressed with Power MOS 7TM by significantly lowering RDS(ON) and Qg. Power MOS 7TM combines lower conduction and switching losses along with exceptionally fast switching speeds inherent with APT's patented metal gate structure. • Lower Input Capacitance • Lower Miller Capacitance • Lower Gate Charge, Qg MAXIMUM RATINGS Symbol VDSS ID IDM VGS VGSM PD TJ,TSTG TL IAR EAR EAS Parameter Drain-Source Voltage SO ISOTOP ® 2 T- 27 "UL Recognized" • Increased Power Dissipation • Easier To Drive • Popular SOT-227 Package • FAST RECOVERY BODY DIODE D G S All Ratings: TC = 25 [ ... ]
