This document introduces the STP7NC70Z and STB7NC70Z series of N-channel 700V power MOSFETs, which have a typical on-resistance of 1.1Ω, extremely high dv/dt and capacitance capability, and integrated back-to-back Zener diodes. They are mainly used in single-ended SMPS, monitors, computers, industrial equipment, and welding equipment.
The STP7NC70Z family are 700 V N‑channel MOSFETs featuring back‑to‑back Zener diodes between gate and source for enhanced ESD protection and very low gate‑input resistance. They are designed for single‑switch applications such as SMPS, monitors, computers, industrial equipment and welding devices.
The document provides absolute maximum ratings, detailed electrical characteristics (VDS = 700 V, ID = 6 A continuous, PD = 125 W, RDS(on) ≈ 1.38 mΩ), thermal data (RθJC = 1.3 °C/W), avalanche ratings, switching times, safe operating area curves, mechanical dimensions for TO‑220, D2PAK and TO‑220FP packages, and packaging/shipping information.
