AO4286

Overview

The AO4286 is a 100V N-Channel MOSFET manufactured by Alpha & Omega Semiconductor Inc. in an SOIC-8 package. It features a maximum continuous drain current of 4A at VGS=10V and a maximum pulsed drain current of 25A. The device exhibits a static drain-source on-resistance of less than 68mΩ at VGS=10V and less than 92mΩ at VGS=4.5V. Electrical characteristics include a gate threshold voltage ranging from 1.7V to 2.9V, a total gate charge of 5.8nC to 10nC at 10V, and input capacitance of 390pF. Thermal performance specifies a junction-to-ambient thermal resistance of 85°C/W and a maximum junction temperature range of -55°C to 150°C.

Feature Summary

Utilizes trench MOSFET technology optimized for high-frequency switching efficiency with minimized conduction and switching power losses.
Features extremely low combinations of RDS(ON), Ciss, and Coss to enhance overall device performance.
Includes 100% Unclamped Inductive Switching (UIS) testing capability.

Applications

Boost converters
Synchronous rectifiers
Consumer power supplies
Telecom power supplies
Industrial power supplies
LED backlighting

Procurement Notes

Verify the specific revision status and datasheet version before procurement, as specifications may be subject to change without notice. Confirm that the intended application does not involve life support devices or systems, as such usage is explicitly unauthorized by the manufacturer. Ensure compliance with all applicable export control rules and regulations relevant to your jurisdiction prior to ordering.

Selection Notes

Select this component when a 100V rating is required alongside efficient high-frequency switching capabilities. The logic-level gate drive compatibility allows operation at VGS=4.5V, making it suitable for lower voltage control interfaces. Consider the thermal constraints provided by the SOIC-8 package and the specified junction-to-ambient resistance for proper heat dissipation design in the target application.
