APT51F50J 500V, 51A, 0.075 Max, t 310ns rr N-Channel FREDFET Power MOS 8 is a high speed, high voltage N-channel switch-mode power MOSFET. This FREDFET version has a drain-source (body) diode that has been optimized for high reliability in ZVS phase shifted bridge and other circuits through reduced t , soft rr recovery, and high recovery dv/dt capability. Low gate charge, high gain, and a greatly UL Recognize reduced ratio of C /C result in excellent noise immunity and low switching loss. The rss iss file E145592 ISOTOP intrinsic gate resistance and capacitance of the poly-silicon gate structure help control APT51F50J di/dt during switching, resulting in low EMI and reliable paralleling, even when switching Single die FREDFET at very high frequency. FEATURES TYPICAL APPLICATIONS Fast switching with low EMI ZVS phase shifted and other full bridge Low t for high reliability Half bridge rr Ultra low C for improved noise immunity PFC and other boost converter rss Low gate charge Buck converter Avalanche energy rated Single and two switch forward RoHS compliant Flyback Absolute Maximum Ratings Symbol Parameter Ratings Unit Continuous Drain Current T = 25C 51 C I D Continuous Drain Current T = 100C 32 A C 1 I Pulsed Drain Current 230 DM V Gate-Source Voltage 30 V GS E 2 1580 Single Pulse Avalanche Energy mJ AS I 37 AR Avalanche Current, Repetitive or Non-Repetitive A Thermal and Mechanical Characteristics Min Typ Max Unit Symbol Characteristic P Total Power Dissipation T = 25C W 480 D C R Junction to Case Thermal Resistance 0.26 JC C/W R Case to Sink Thermal Resistance, Flat, Greased Surface 0.15 CS T ,T Operating and Storage Junction Temperature Range C -55 150 J STG V V RMS Voltage (50-60hHz Sinusoidal Waveform from Terminals to Mounting Base for 1 Min.) 2500 Isolation oz 1.03 W T Package Weight g 29.2 inlbf 10 Torque Terminals and Mounting Screws.
