SGS-Thomson STP7NB40 / STP7NB40FP PowerMESH MOSFET Datasheet

Datasheet 4 pages · 112 KB · EN

The STP7NB40 and STP7NB40FP are N‑channel enhancement mode PowerMESH™ MOSFETs built with SGS‑Thomson's high‑voltage MESH OVERLAY™ process. The devices feature a patented strip layout and edge termination that provide very low on‑state resistance, high avalanche capability and minimized gate charge.

The datasheet lists absolute maximum ratings, thermal data, avalanche characteristics and a full set of electrical parameters such as drain‑source voltage, continuous drain current, total dissipation, capacitances and switching times. Typical applications include high‑current, high‑speed switching, SMPS, DC‑AC converters for welding, UPS and motor‑drive systems.
