AOD5N40 Description

Short technical summary and product information.

The AOD5N40 is an N-Channel MOSFET from Alpha & Omega Semiconductor, designed for high voltage applications. It features a drain-source breakdown voltage of 400V minimum at 25°C and 500V at 150°C. The continuous drain current is rated at 4.2A at 25°C case temperature, with a maximum on-resistance of 1.6Ω at Vgs=10V. Typical gate charge is 6.9nC, enabling fast switching with turn-on delay of 16.5ns and turn-off delay of 24ns. The device is 100% UIS tested for avalanche capability, with single pulsed avalanche energy of 86mJ. It is available in a TO-252 (DPAK) surface mount package. This MOSFET is suitable for AC-DC power supplies, offline flyback converters, and other high voltage switching applications. It is RoHS3 compliant (unverified) and has an MSL of Level 1.
