STW4N150
The STW4N150 is a high-voltage N-channel power MOSFET designed for industrial and energy applications. It has a drain-source voltage of 1500 V and a continuous current rating of 4 A, providing stable switching performance in circuits that require high breakdown voltage and thermal reliability. The PowerMESH / MESH OVERLAY™ structure lowers on-resistance to approximately 5 Ω, reducing conduction losses and supporting efficient operation.
This MOSFET is suitable for high-frequency switching due to its fast switching speed and low gate charge, and is typically used in solar inverters, wind power systems, electric vehicle power units, and telecom equipment. Its TO-247 package offers mechanical stability and effective heat dissipation.
The STW4N150 is 100% avalanche-tested, ensuring it can handle voltage transients reliably. It is appropriate for industrial control systems, battery management circuits, and other applications requiring stable operation under high voltage and varying environmental conditions.
