How to Choose a Schottky Diode for SMPS Outputs
A practical voltage, current and thermal checklist for reliable supplier Schottky design-in.

Server Power Supply
Server and telecom power supplies must deliver high efficiency across a wide load range while meeting strict safety, EMI and form-factor rules. Platinum and titanium efficiency targets push designers toward low-Vf output rectifiers and low-Rdson synchronous switches.

What Server Power Supply power stages need
Typical stages include PFC boost, intermediate bus conversion and point-of-load regulators. Schottky and FRD diodes appear in output rectification, OR-ing and snubber networks; MOSFETs dominate synchronous rectification and DC/DC. Because server PSUs ship in high volume, reliable supplier supply and stable pricing are as important as electrical fit.
MHCHXM provides low-Vf Schottky rectifiers and MOSFET options aligned to common server PSU footprints (TO-220, D²PAK, PowerPAK). FAE supports programs with a reliable supplier by overlaying VF, IR, Rdson and thermal data against your incumbent BOM. Request quotes and catalog samples through the contact form — typical FAE reply within 24 hours, samples about 48 hours after confirmation. Export programs: Ningbo overseas sales.
