UniFET TM FDA20N50 / FDA20N50_F109 500V N-Channel MOSFET Features Description • 22A, 500V, RDS(on) = 0.23Ω @VGS = 10 V These N-Channel enhancement mode power field effect transistors are produced using Fairchild’s proprietary, planar stripe, DMOS technology. • Low gate charge ( typical 45.6 nC) • Low Crss ( typical 27 pF) This advanced technology has been especially tailored to minimize on-state resistance, provide superior switching performance, and withstand high energy pulse in the avalanche and commutation mode. These devices are well suited for high efficient switched mode power supplies and active power factor correction. • Fast switching • 100% avalanche tested • Improved dv/dt capability D G TO-3P FDA Series G DS S Absolute Maximum Ratings Symbol Parameter VDSS Drain-Source Voltage ID Drain Current - Continuous (TC = 25°C) - Continuous (TC = 100°C) IDM Drain Current - Pulsed FDA20N50 Unit 500 V 22 13.2 A A (Note 1) 88 A ± 30 V 1110 mJ VGSS Gate-Source voltage EAS Single Pulsed Avalanche Energy (Note 2) IAR Avalanche Current (Note 1) 22 A EAR Repetitive Avalanche Energy (Note 1) 28.0 mJ dv/dt Peak Diode Recovery dv/dt (Note 3) PD Power Dissipation TJ, TSTG Operating and Storage Temperature Range TL Maximum Lead Temperature for Soldering Purpose, 1/8” from Case for 5 Seconds 20 V/ns 280 2.3 W W/°C -55 to +150 °C 300 °C (TC = 25°C) - Derate above 25°C * Drain current limited by maximum junction termperature.

ANTI-COUNTERFEITING POLICY Fairchild Semiconductor Corporation’s Anti-Counterfeiting Policy. Fairchild’s Anti-Counterfeiting Policy is also stated on our external website, www.Fairchildsemi.com, under Sales Support. Counterfeiting of semiconductor parts is a growing problem in the industry. All manufactures of semiconductor products are experiencing counterfeiting of their parts. Customers who inadvertently purchase counterfeit parts experience many problems such as loss of brand reputation, substandard performance, failed application, and increased cost of production and manufacturing delays. Fairchild is taking strong measures to protect ourselves and our customers from the proliferation of counterfeit parts. Fairchild strongly encourages customers to purchase Fairchild parts either directly from Fairchild or from Authorized Fairchild Distributors who are listed by country on our web page cited above. Products customers buy either from Fairchild directly or from Authorized Fairchild Distributors are genuine parts, have full traceability, meet Fairchild’s quality standards for handing and storage and provide access to Fairchild’s full range of up-to-date technical and product information. Fairchild and our Authorized Distributors will stand behind all warranties and will appropriately address and warranty issues that may arise. Fairchild will not provide any warranty coverage or other assistance for parts bought from Unauthorized Sources. Fairchild is committed to combat this global problem and encourage our customers to do their part in stopping this practice by buying direct or from authorized distributors.
