MTD3055VL N-Channel Logic Level Enhancement Mode Field Effect Transistor General Description Features This N-Channel Logic Level MOSFET has been designed specifically to improve the overall efficiency of DC/DC converters using either synchronous or conventional switching PWM controllers. 12 A, 60 V. RDS(ON) = 0.18 @ VGS = 5 V Critical DC electrical parameters specified at elevated temperature. Low drive requirements allowing operation directly from logic drivers. Vgs(th) < 2 V. These MOSFETs feature faster switching and lower gate charge than other MOSFETs with comparable RDS(ON) specifications. Rugged internal source-drain diode can eliminate the need for an external Zener diode transient suppressor. 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. 175C maximum junction temperature rating.

RJA is the sum of the junction-to-case and case-to-ambient thermal resistance where the case thermal reference is defined as the drain tab. RJC is guaranteed by design while RCA is determined by the user's board design. a) RJA= 38oC/W when mounted on a 1 in2 pad of 2oz copper. b) RJA= 96oC/W when mounted on a minimuim pad.
