General Description
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.
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
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.
Rugged internal source-drain diode can eliminate the
need for an external Zener diode transient suppressor.
 175°C maximum junction temperature rating.

Notes:
1. RθJA 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.
RθJC is guaranteed by design while RθCA is determined by the user's board design.
Scale 1 : 1 on letter size paper
2. Pulse Test: Pulse Width 300 µs, Duty Cycle 2.0%
a) RθJA= 38oC/W when mounted on a
1 in2 pad of 2oz copper.
b) RθJA= 96oC/W when mounted on a
minimuim pad.
