At 2.7 A and 10 V gate drive, the STP7NK40Z exhibits a maximum on-resistance of 1 Ohm. ## Through-hole TO-220 — field-service and prototyping fit The TO-220-3 package (Supplier Device Package TO-220) is a through-hole footprint with a screw-mounting hole in the tab. It accepts a standard M3 screw for heatsink attachment. The through-hole form factor simplifies hand-soldering, rework, and field replacement — a practical choice for low-to-mid volume production, prototyping, and maintenance spares where surface-mount reflow is not available. The base product number is STP7NK40; the 'Z' suffix indicates the SuperMESH™ generation.","metaTitle":"STMicroelectronics STP7NK40Z N-Channel MOSFET","metaDescription":"STP7NK40Z N-channel 400V 5.4A MOSFET in TO-220.
