Product details

The 600 V rating gives headroom for universal-input offline flyback converters (up to 400 VDC bus) and 3-phase rectified industrial rails. The 4 A continuous current is specified at Tc=25 °C; at elevated case temperatures the current must be derated per the datasheet's power dissipation curve.

On-resistance and gate charge — conduction vs switching loss trade-off

This is a moderate on-resistance for a 600 V device — the part is suited to resonant or quasi-resonant topologies where switching losses dominate the thermal budget, not conduction losses.

D2PAK package — thermal and layout considerations

The STB4NK60ZT4 is supplied in the D2PAK (TO-263) surface-mount package, with the exposed drain tab on the top side.

The part is ROHS3 compliant.

Frequently asked questions

What is the equivalent of STB4NK60ZT4?

The STB4NK60ZT4 is a specific SuperMESH™ variant; any replacement would require verifying Rds(on), gate charge, and package footprint against the application's switching and thermal requirements.

Is STB4NK60ZT4 RoHS compliant?

Yes, the STB4NK60ZT4 is ROHS3 compliant.
