Product details

Gate charge and switching speed — 170 nC at 10 V

Total gate charge is 170 nC at Vgs = 10 V, with an input capacitance of 9000 pF at Vds = 25 V. This moderate gate charge means a gate-driver capable of sourcing 1 A peak can switch the FET in the tens of nanoseconds; the designer should budget gate-drive power as Qg × Vgs × fsw for the target frequency.

Package and mounting — D²PAK (TO-263) surface mount

The STB170NF04 is supplied in the D²PAK (TO-263) surface-mount package, a 2-lead plus tab design.

Frequently asked questions

Does STB170NF04 require a heatsink?

The D²PAK package is designed to dissipate heat through the exposed drain tab soldered to a PCB copper plane. For continuous operation at high current, a heatsink or adequate PCB copper area is recommended to keep the junction temperature within the -55°C to 175°C range.
