Where MBR10100 fits
MBR10100 is an MHCHXM low-forward-drop Schottky rectifier. The published catalog rating is 10 A average forward current and 100 V repetitive reverse voltage (VRRM), in a TO-220AB package. It is the kind of diode used on switch-mode supply outputs, as a freewheeling diode, and in DC-DC stages where conduction loss matters more than reverse recovery.
Ratings to overlay before a drop-in
The product page lists a typical forward voltage of 0.75 V and a junction-temperature window of 150–175 °C. Matching the 10 A / 100 V class is only the first screen. Compare forward drop against current at the junction temperature you actually run, reverse leakage at the working reverse voltage, surge current, and the TO-220AB outline, including lead form and the mounting tab. Those items decide whether the part can replace an incumbent device without a board change.
Loss and voltage margin
At 10 A, a typical 0.75 V drop is already several watts of conduction loss, so the heat sink and copper area usually limit usable current before the silicon rating does. Keep reverse voltage, including ringing, inside the 100 V class with margin. Schottky leakage rises quickly with temperature, so check reverse current at the highest expected junction temperature, not only at 25 °C.
MHCHXM builds this Schottky family in Wuxi. Catalog samples are typically prepared in about 48 hours after stock and the specification are confirmed. When you request a quote or a datasheet, include the application, the voltage and current, and the package.
