AO3400 N-Channel Enhancement Mode Field Effect Transistor
General Description
The AO3400 uses advanced trench technology to provide excellent RDS(ON), low gat

e charge and operation with gate voltages as low as 2.5V. This device is suitable for use as a load switch or in PWM applications. Standard Product AO3400 is Pb-free (meets ROHS & Sony 259 specifications). AO3400L is a Green Product ordering option. AO3400 and AO3400L are electrically identical.

Features
VDS (V) = 30V ID = 5.8 A (VGS = 10V) RDS(ON) < 28m? (VGS = 10V) RDS(ON) < 33m? (VGS = 4.5V) RDS(ON) < 52m? (VGS = 2.5V)

A: The value of R θJA is measured with the device mounted on 1in2 FR-4 board with 2oz. Copper, in a still air environment with TA =25°C. The value in any given application depends on the user's specific board design. The current rating is based on the t≤ 10s thermal resistance rating. B: Repetitive rating, pulse width limited by junction temperature. C. The R θJA is the sum of the thermal impedence from junction to lead RθJL and lead to ambient. D. The static characteristics in Figures 1 to 6,12,14 are obtained using 80?s pulses, duty cycle 0.5% max. E. These tests are performed with the device mounted on 1 in2 FR-4 board with 2oz. Copper, in a still air environment with TA=25°C. The SOA curve provides a single pulse rating. Rev 4 : June 2005 THIS PRODUCT HAS BEEN DESIGNED AND QUALIFIED FOR THE CONSUMER MARKET.
