Product details

600 V, 2.4 A — what the SuperMESH™ ratings mean for your offline supply

The STD3NK60ZT4: Its 600 V drain-source breakdown voltage (Vdss) provides headroom for universal-input AC-DC stages. Gate charge (Qg) is 11.8 nC at 10 V. Input capacitance (Ciss) of 311 pF at 25 V drain-source helps keep switching losses low.

NRND status — plan your last-time-buy or select a replacement now

This means STMicroelectronics is not actively promoting this part for new projects. For existing BOM lines, you have two paths: secure last-time-buy (LTB) inventory through the independent channel while stock remains available, or qualify a pin-compatible replacement. The base product number is STD3NK60, and parts sharing this base (STD3NK60Z, STD3NK60T4) are in the same SuperMESH™ family — but confirm pin compatibility and parametric overlap from the datasheet before swapping.

DPAK footprint and thermal reality

The TO-252 (DPAK) surface-mount package with two leads and a tab is the standard medium-power SMD footprint. Power dissipation is 45 W (Tc).

Frequently asked questions

Is STD3NK60ZT4 obsolete?

It is not yet discontinued, but ST is no longer actively promoting it for new designs. Existing production can continue with LTB planning, but new projects should select a current-production alternative.

What is the replacement for STD3NK60ZT4?

The base product number STD3NK60 covers several variants (STD3NK60Z, STD3NK60T4) in the same SuperMESH™ family — these are potential drop-in candidates but require datasheet verification of Rds(on), gate charge, and package compatibility. For a current-production alternative, evaluate ST's active 600 V SuperMESH™ portfolio in DPAK, such as the STD4NK60Z or STD5NK60Z series, which offer similar or improved ratings.

Is STD3NK60ZT4 compatible with STP3NK60Z?

The STP3NK60Z is a TO-220 through-hole variant of the same SuperMESH™ die. The electrical ratings (600 V Vdss, 2.4 A Id, 3.6 Ω Rds(on)) are identical, but the package is different — STP3NK60Z is through-hole, STD3NK60ZT4 is surface-mount DPAK. They are not drop-in compatible on the same PCB footprint, but the die-level performance is the same if you can accommodate the different package.
