AOI4N60

Mosfets Overview

The AOI4N60 is a single N-channel MOSFET from Alpha & Omega Semiconductor Inc., designed for surface-mount applications in the TO-251A package. It features a drain-source voltage (Vdss) of 600 V and a continuous drain current (Id) of 4 A at case temperature. The device exhibits a maximum on-resistance (Rds(on)) of 3.5 ohms at 10 V gate drive and 2 A drain current. Key electrical parameters include a gate threshold voltage (Vgs(th)) of 4.5 V max at 250 µA, a maximum gate charge (Qg) of 12 nC at 10 V, and an input capacitance (Ciss) of 370 pF at 25 V. Power dissipation is rated at 104 W at case temperature, with an operating junction temperature range of -55°C to 150°C.

Mosfets Procurement Notes

Verify the specific package variant, as AOI4N60 typically denotes the TO-251A surface-mount version. Confirm RoHS compliance status with the manufacturer or authorized distributor prior to ordering. Ensure that the procurement channel provides original components with traceable documentation to guarantee authenticity and performance reliability for critical power electronics designs.

Mosfets Selection Notes

Select the AOI4N60 when a 600 V N-channel MOSFET is required in a compact TO-251A footprint. Compare its 3.5 ohm Rds(on) against alternative devices if lower conduction losses are critical. Consider the 4 A current rating relative to the expected load and thermal management capabilities of the PCB design to ensure operation within the specified junction temperature limits.
