General Description
The AOB405 uses advanced trench technology to
provide excellent R
DS(ON)
, low gate charge and low
gate resistance. With the excellent thermal resistance
of the D2PAK package, this device is well suited for
high current load applications.
Standard Product
AOB405 is Pb-free (meets ROHS & Sony 259
specifications). AOB405L is a Green Product ordering
option. AOB405 and AOB405L are electrically
identical.

A: The value of R qJA is measured with the device mounted on 1in 2 FR-4 board with 2oz. Copper, in a still air environment with T A =25C. The Power
dissipation PDSM is based on R qJA and the maximum allowed junction temperature of 150C. The value in any given application depends on the user's
specific board design, and the maximum temperature of 175C may be used if the PCB allows it.
B. The power dissipation PD is based on TJ(MAX)=175C, 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)=175C.
D. The R qJA is the sum of the thermal impedence from junction to case R qJC 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 the device mounted to a large heatsink, assuming a
maximum junction temperature of TJ(MAX)=175C.
G. The maximum current rating is limited by bond-wires.
H. These tests are performed with the device mounted on 1 in 2 FR-4 board with 2oz. Copper, in a still air environment with TA=25C. The SOA curve
provides a single pulse rating.
