Overview
The STW9NK70Z is a high-performance N-Channel Power MOSFET from STMicroelectronics, part of the SuperMESH™ series. This device is optimized using ST's well-established strip-based PowerMESH™ layout, which significantly reduces on-resistance and enhances dv/dt capability. The STW9NK70Z is designed for high current, high speed switching applications and is ideal for use in off-line power supplies, adaptors, and power factor correction (PFC) circuits.
