Product details

Gate charge of 56 nC at 10 V is moderate; a standard gate-drive IC or a driver transformer can drive it without excessive switching loss at frequencies up to 100 kHz or so.

That extra headroom matters when the part sits near a hot transformer or in a sealed outdoor PSU where ambient can push 85 °C and the junction sees another 40 °C rise from dissipation.

ST lists the STP7NK80Z as Active. For a BOM line, this part carries no LTB risk and is suitable for qualification into new designs. The base product number STP7NK80 covers the family; the Z suffix denotes the SuperMESH generation.

Frequently asked questions

Is STP7NK80Z obsolete?

No — the lifecycle status is Active, meaning ST continues to manufacture it with no discontinuation notice. It is suitable for both production and new designs.

What is the equivalent of STP7NK80Z?

No pin-compatible equivalent is listed in the official record. The 800 V, 5.2 A, TO-220 parametric window is common across several MOSFET families from Infineon, onsemi, and others — a cross-reference search against those specs will surface candidates for qualification.
