TO-247 APT24F50B APT24F50S 500V, 24A, 0.24 Max, t 210ns rr N-Channel FREDFET Power MOS 8 is a high speed, high voltage N-channel switch-mode power MOSFET. 3 D PAK 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 reduced ratio of C /C result in excellent noise immunity and low switching loss. The rss iss APT24F50B APT24F50S intrinsic gate resistance and capacitance of the poly-silicon gate structure help control di/dt during switching, resulting in low EMI and reliable paralleling, even when switching at very high frequency. Single die FREDFET 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 24 C I D Continuous Drain Current T = 100C 15 A C 1 I Pulsed Drain Current 82 DM V Gate-Source Voltage 30 V GS E 2 495 Single Pulse Avalanche Energy mJ AS I 11 AR Avalanche Current, Repetitive or Non-Repetitive A Thermal and Mechanical Characteristics Min Typ Max Unit Symbol Characteristic P Total Power Dissipation T = 25C 335 W D C R 0.37 Junction to Case Thermal Resistance JC C/W R 0.15 Case to Sink Thermal Resistance, Flat, Greased Surface CS T ,T Operating and Storage Junction Temperature Range -55 150 J STG C T Soldering Temperature for 10 Seconds (1.6mm from case) 300 L oz 0.22 W Package Weight T g 6.2 inlbf 10 Torque Mounting Torque ( TO-247 Package), 6-32 or M3 screw 1.1 Nm Microsemi Website - Static Characteristics T = 25C unless otherwise speci ed AP24F50B S J Symbol Parameter Test Conditions Min Typ Max Unit V V = 0V, I = 250A Drain-Source Breakdown Voltage 500 V BR(DSS) GS D V /T Reference to 25C, I = 250A Breakdown Voltage Temperature Coef cient 0.60 V/C BR(DSS) J D V = 10V, I = 11A R 3 Drain-Source On Resistance 0.21 0.24 DS(on) GS D V Gate-Source Threshold Voltage 2.5 4 5 V GS(th) V = V , I = 1mA GS DS D V /T Threshold Voltage Temperature Coef cient -10 mV/C GS(th) J V = 500V T = 25C 250 DS J I Zero Gate Voltage Drain Current A DSS V = 0V T = 125C 1000 GS J V = 30V I Gate-Source Leakage Current 100 nA GSS GS Dynamic Characteristics T = 25C unless otherwise speci ed J Symbol Parameter Test Conditions Min Typ Max Unit g V = 50V, I = 11A fs Forward Transconductance 17 S DS D C Input Capacitance 3630 iss V = 0V, V = 25V GS DS C Reverse Transfer Capacitance 50 rss f = 1MHz C Output Capacitance 390 oss pF 4 C Effective Output Capacitance, Charge Related 225 o(cr) V = 0V, V = 0V to 333V GS DS 5 C Effective Output Capacitance, Energy Related 115 o(er) Q Total Gate Charge 90 g V = 0 to 10V, I = 11A, GS D Q Gate-Source Charge 21 nC gs V = 250V DS Q Gate-Drain Charge gd 41 t Resistive Switching Turn-On Delay Time 16 d(on) t V = 333V, I = 11A Current Rise Time 19 r DD D ns 6 t R = 4.7 , V = 15V Turn-Off Delay Time 41 d(off) G GG t Current Fall Time 14 f Source-Drain Diode Characteristics Symbol Parameter Test Conditions Min Typ Max Unit Continuous Source Current MOSFET symbol I S 24 showing the (Body Diode) integral reverse p-n A Pulsed Source Current junction diode I SM 82 (body diode) 1 (Body Diode) V I = 11A, T = 25C, V = 0V Diode Forward Voltage 1. 2 V SD SD J GS T = 25C 210 J t Reverse Recovery Time ns rr T = 125C 400 J 3 I = 11A T = 25C 0.68 SD J Q Reverse Recovery Charge C rr di /dt = 100A/s T = 125C 1.64 SD J V = 100V T = 25C 7.1 DD J I Reverse Recovery Current A rrm T = 125C 9.7 J I 11A, di/dt 1000A/s, V = 333V, SD DD dv/dt Peak Recovery dv/dt V/ns 20 T = 125C J 1 Repetitive Rating: Pulse width and case temperature limited by maximum junction temperature. 2 Starting at T = 25C, L = 8.18mH, R = 25, I = 11A.
