Frequently Asked Questions
What is the maximum forward voltage of the STPST5H100SFY at its rated current?
The STPST5H100SFY has a maximum forward voltage of 0.68 V at 5 A forward current, with a typical value of 0.55 V. This low VF reduces conduction losses and heat dissipation in rectifier and freewheeling diode circuits operating at up to 100 V.
Which automotive power converter topologies are best suited for the STPST5H100SFY?
This rectifier suits freewheeling diode positions in synchronous buck converters, boost converters, and H-bridge motor drives running from a 12 V or 24 V automotive bus with peak transients up to 100 V. Its AEC-Q101 qualification and -40°C to +175°C operating range satisfy under-hood reliability requirements.
How does the TO-277A package of the STPST5H100SFY help with thermal management on a PCB?
The TO-277A (D2PAK flat lead) package provides a large exposed copper drain pad that transfers heat directly to the PCB copper plane, enabling efficient conduction cooling without a separate heatsink. At 5 A continuous current and a junction-to-case thermal resistance typical of TO-277A, the package supports high-power-density layouts in automotive modules.
Is STPST5H100SFY a suitable drop-in alternative to a through-hole 5 A Schottky rectifier in a redesign targeting surface-mount assembly?
Yes. The STPST5H100SFY delivers the same 100 V / 5 A ratings as many axial or DO-201 rectifiers while occupying a low-profile TO-277A surface-mount footprint. The AEC-Q101 grade and -40°C to +175°C temperature range ensure it meets or exceeds the reliability standards of standard commercial through-hole devices.
