The document introduces the features and characteristics of the STP7NC70Z and STB7NC70Z series products, including N-CHANNEL 700V power MOSFETs, extremely high dv/dt and capability, and PowerMESH™III technology with Zener protection.
The STP7NC70Z, STP7NC70ZFP, STB7NC70Z and STB7NC70Z‑1 are 700 V N‑channel MOSFETs featuring back‑to‑back gate‑source Zener diodes for enhanced ESD protection and low gate charge. They are offered in TO‑220, D2PAK, and TO‑220FP packages with very low on‑resistance and high avalanche capability.
These devices are intended for single‑ended SMPS in monitors, computers and industrial equipment, as well as welding equipment. The datasheet lists absolute maximum ratings, electrical characteristics, thermal data, mechanical dimensions, and safe operating area curves to aid designers in selecting the appropriate part.
