IRFI840G www.vishay.com Vishay Siliconix Power MOSFET FEATURES D TO-220 FULLPAK Isolated package High voltage isolation = 2.5 kV (t = 60 s RMS f = 60 Hz) Sink to lead creepage distance = 4.8 mm G Dynamic dV/dt rating Low thermal resistance SS S Material categorization: for definitions of compliance DD G please see www.vishay.com/doc 99912 N-Channel MOSFET DESCRIPTION PRODUCT SUMMARY Third generation power MOSFETs from Vishay provide the designer with the best combination of fast switching, V (V) 500 DS ruggedized device design, low on-resistance and R ()V = 10 V 0.85 DS(on) GS cost-effectiveness. Q (Max.) (nC) 67 g The TO-220 FULLPAK eliminates the need for additional Q (nC) 10 gs insulating hardware in commercial-industrial applications. The molding compound used provides a high isolation Q (nC) 34 gd capability and a low thermal resistance between the tab and Configuration Single external heatsink. The isolation is equivalent to using a 100 micron mica barrier with standard TO-220 product. The FULLPAK is mounted to a heatsink using a single clip or by a single screw fixing.
