STP7NK40Z-STP7NK40ZFP-STD7NK40Z-STD7NK40Z-1 is a N-channel 400V-0.85Ω-5.4A MOSFET produced by ST company. Its features include typical RDS(on)=0.85Ω, extremely high dv/dt capability, 100% avalanche tested, minimized gate charge, very low intrinsic capacitance and very good manufacturing repeatability. This series of products can be used in high current, high speed switching, offline power supplies, adapters and PFC applications.
The STP7NK40Z, STP7NK40ZFP, STD7NK40Z and STD7NK40Z‑1 are N‑channel 400 V, 5.4 A SuperMESH™ power MOSFETs offered in TO‑220, TO‑220FP, DPAK and IPAK packages. The devices feature very low on‑resistance, high dv/dt capability and built‑in gate‑source Zener diodes for ESD protection.
