Product Introduction

Overview

The STP9NK70ZFP 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 STP9NK70ZFP 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. It features built-in Zener diodes for gate-source protection, improved ESD capability, and minimized gate charge, making it a reliable choice for demanding power management tasks.
