STW4N150 1500V 4A N-Channel MOSFET

STW4N150 Transistor 1500V 4A N-Channel Power MOSFET

The STW4N150 is a high-voltage N-channel power MOSFET developed by STMicroelectronics, designed for reliable switching in demanding industrial and energy systems. With a drain-source voltage rating of 1500V and a continuous drain current of 4A, it delivers stable performance in circuits requiring high breakdown strength and thermal efficiency.

This transistor uses PowerMESH and MESH OVERLAY technology, which reduces R\DS\(on) to just 5Ω, minimizing conduction losses and supporting energy-efficient operation. Its fast switching speed and reduced gate charge make it ideal for high-frequency power conversion, while the TO-247 package ensures mechanical robustness and effective heat dissipation.

Engineered for durability, the STW4N150 undergoes 100% avalanche testing to meet strict reliability standards. It is suitable for solar inverters, wind power systems, electric vehicle power units, and telecom equipment, where long-term stability under high voltage is essential. Its performance in harsh environments makes it a strong choice for automation systems, battery management circuits, and other industrial control applications.
