AOB403 P-Channel Enhancement Mode Field Effect Transistor
General Description
The AOB403 uses advanced trench technology to provide excellent RDS(ON), low gate charge and low gate resistance. With the excellent thermal resistance of the D2-PAK package, this device is well suited for high current load applications. Standard product AOB403 is Pb-free (meets ROHS & Sony 259 specifications). AOB403L is a Green Product ordering option. AOB403 and AOB403L 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. Rev1:May2005 THIS PRODUCT HAS BEEN DESIGNED AND QUALIFIED FOR THE CONSUMER MARKET.
