| FDT3612 March 2001 FDT3612 100V N-Channel PowerTrench MOSFET General Description This N-Channel MOSFET has been designed specifically to improve the overall efficiency of DC/DC converters using either synchronous or conventional switching PWM controllers. These MOSFETs feature faster switching and lower gate charge than other MOSFETs with comparable RDS(ON) specifications. The result is a MOSFET that is easy and safer to drive (even at very high frequencies), and DC/DC power supply designs with higher overall efficiency. Features * 3.7 A, 100 V. RDS(ON) = 120 m @ VGS = 10 V RDS(ON) = 130 m @ VGS = 6 V * Fast switching speed * Low gate charge (14nC typ) * High performance trench technology for extremely low RDS(ON) * High power and current handling capability in a widely used surface mount package Applications * DC/DC converter * Motor driving D D D D S D SOT-223 S G G D S SOT-223* (J23Z) G G S Absolute Maximum Ratings Symbol VDSS VGSS ID PD Drain-Source Voltage Gate-Source Voltage Drain Current - Continuous - Pulsed Maximum Power Dissipation TA=25oC unless otherwise noted Parameter Ratings 100 20 (Note 1a) Units V V A W 3.7 20 3.0 1.3 1.1 -55 to +150 (Note 1a) (Note 1b) (Note 1c) TJ, TSTG Operating and Storage Junction Temperature Range C Thermal Characteristics RJA RJC Thermal Resistance, Junction-to-Ambient Thermal Resistance, Junction-to-Case (Note 1a) (Note 1) 42 12 C/W C/W Package Marking and Ordering Information Device Marking 3612 2001 Fairchild Semiconductor Corporation Device FDT3612 Reel Size 13'' Tape width 12mm Quantity 2500 units FDT3612 Rev.
