N-Channel Enhancement Mode Field Effect Transistor
General Description
Features
The AOD494 uses advanced trench technology to
provide excellent RDS(ON), low gate charge.This device
is suitable for use as a high side switch in SMPS and
general purpose applications. Standard Product
AOD494 is Pb-free (meets ROHS & Sony 259
specifications). AOD494L is a Green Product ordering
option. AOD494 and AOD494L are electrically
identical.

A: The value of RθJA is measured with the device in a still air environment with T A =25°C.
B. The power dissipation PD is based on TJ(MAX)=175°C, using junction-to-case thermal resistance, and is more useful in setting the upper
dissipation limit for cases where additional heatsinking is used.
C: Repetitive rating, pulse width limited by junction temperature TJ(MAX)=175°C.
D. The RθJA is the sum of the thermal impedence from junction to case RθJC and case to ambient.
E. The static characteristics in Figures 1 to 6 are obtained using <300 ms pulses, duty cycle 0.5% max.
F. These curves are based on the junction-to-case thermal impedence which is measured with the120
device mounted to a large heatsink, assumin
a maximum junction temperature of TJ(MAX)=175°C.
G. These tests are performed with the device mounted on 1 in 2 FR-4 board with 2oz. Copper, in a still air environment with T A=25°C. The
SOA curve provides a single pulse rating.
H. Surface mounted on a 1 in 2 FR-4 board with 2oz. Copper.
