AO3400

N-Channel Enhancement Mode Field Effect Transistor

General Description

The AO3400 uses advanced trench technology to

provide excellent R

DS(ON)

, low gate 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.

A: The value of R

θJA

is measured with the device mounted on 1in FR-4 board with 2oz. Copper, in a still air environment with T

A

=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 R

θJL

and lead to ambient.

D. The static characteristics in Figures 1 to 6,12,14 are obtained using 80 µs pulses, duty cycle 0.5% max.

2

E. These tests are performed with the device mounted on 1 in FR-4 board with 2oz. Copper, in a still air environment with T

A

=25°C. The

SOA curve provides a single pulse rating.
