AOU4N60

Single FETs, MOSFETs Overview

The AOU4N60 is a 600V N-Channel MOSFET from Alpha & Omega Semiconductor, packaged in TO-252. It features a maximum continuous drain current of 4A at TC=25°C and a pulsed drain current of 14A. The device guarantees an on-resistance (RDS(on)) of less than 2.3Ω at VGS=10V and ID=2A. Electrical characteristics include a gate threshold voltage ranging from 3.4V to 4.5V and a total gate charge of up to 14.5nC. Thermal performance specifies a junction-to-case resistance of 1.2°C/W and a junction-to-ambient resistance of 55°C/W. The component supports a junction temperature range of -50°C to 150°C.
