Product details

The 8.5 Ohm maximum on-resistance at 900 mA and 10 V gate drive defines the conduction loss floor for a typical offline flyback primary switch or auxiliary supply rail.

Gate charge and switching — sizing the drive

Total gate charge is 16 nC at 10 V, which keeps the drive current requirement modest — a PWM controller with a 100 mA source/sink capability can switch this FET at 100 kHz without an external driver. Input capacitance is 499 pF at 25 V drain-source, a figure that influences the turn-on delay and the controller's drive impedance selection.

DPAK footprint and thermal path

The base product number is STD2NK100; the 'Z' suffix denotes the lead-free, ROHS-compliant version.

Frequently asked questions

What is the difference between STD2NK100Z and STD2NK100?

The STD2NK100 is the original non-RoHS version. The STD2NK100Z suffix indicates lead-free, ROHS3-compliant construction. Electrical ratings are identical.
