AO4620

Overview

The AO4620 is a complementary enhancement mode field effect transistor featuring an N-channel and P-channel MOSFET in a single SOIC-8 package. The N-channel device supports a drain-source voltage of 30V with a continuous drain current of 7.2A at VGS=10V, while the P-channel device handles -30V and -5.3A at VGS=-10V. On-resistance for the N-channel is less than 24mΩ at VGS=10V and 36mΩ at VGS=4.5V; the P-channel on-resistance is under 32mΩ at VGS=-10V and 55mΩ at VGS=-4.5V. The component operates within a junction temperature range of -55°C to 150°C.

FAQ

What is the maximum repetitive avalanche energy rating?

The datasheet specifies repetitive avalanche energy ratings but does not provide a single universal value; it depends on the specific test conditions and pulse width limitations defined by the junction temperature.

How is the thermal resistance measured?

The Junction-to-Ambient thermal resistance (RqJA) is measured with the device mounted on a 1-inch square FR-4 board with 2oz copper in a still air environment at TA=25°C.

Are there restrictions on using this component in life support systems?

Yes, applications or uses as critical components in life support devices or systems are not authorized by Alpha & Omega Semiconductor.
