Key Features
- 250V breakdown voltage and 17A continuous drain current for medium-voltage power conversion applications
- Maximum RDS(on) of 165mΩ reduces conduction losses in switch-mode power supplies and motor drives
- 100mJ avalanche energy rating ensures robustness during inductive load switching transients
- DPAK (TO-252) surface-mount package with built-in body diode simplifies board layout and thermal design
Applications
The STD17NF25 is suited for medium-voltage power conversion circuits including DC-DC converters, synchronous rectifiers, and motor control modules operating at up to 250V. Its combination of low on-resistance and reasonable avalanche energy tolerance makes it a reliable choice for industrial power supplies, home appliance motor drivers, and electronic lighting ballasts. The DPAK package enables automated PCB assembly with good thermal management through direct solder attachment of the drain pad.

Frequently Asked Questions
What are the voltage and current ratings of the STD17NF25?
The STD17NF25 is rated for a maximum drain-source voltage (VDS) of 250V and a continuous drain current (ID) of 17A at 25°C. These specifications make it a capable choice for medium-voltage switching applications such as DC-DC converters, motor drives, and power factor correction stages.
What is the maximum RDS(on) of the STD17NF25?
The STD17NF25 has a maximum drain-source on-resistance (RDS(on)) of 165mΩ, measured at a gate-source voltage of 10V. This relatively low on-resistance helps minimize conduction losses and thermal dissipation during continuous current operation in power conversion systems.
What package does the STD17NF25 use and what are the assembly benefits?
The STD17NF25 is packaged in a DPAK (TO-252) surface-mount format, which allows efficient reflow soldering in automated production lines. The exposed drain pad on the underside of the package provides a low-resistance thermal path to the PCB, aiding heat dissipation without requiring a separate heatsink.
Can the STD17NF25 handle inductive switching without external protection?
The STD17NF25 features a 100mJ avalanche energy rating (EAS), which provides a degree of built-in protection against transient voltage spikes caused by inductive load switching. While external snubbers or clamps may still be recommended in demanding applications, this avalanche capability enhances system robustness in motor drive and relay control circuits.
