Description

Marked "FFSH 5065A" on the package with the ON Semiconductor logo, this is a Silicon Carbide (SiC) Schottky Diode from onsemi's EliteSiC line, rated 50A/650V in a D1, TO-247-2L package. Silicon Carbide Schottky diodes use a fundamentally different technology than standard silicon diodes, offering superior switching performance and higher reliability. Visually, the two-pin (D1) TO-247 outline with a single black-body imprint and only two active leads (the third pin, if present, is typically unconnected/mechanical) is characteristic of this "-2L" variant.

These diodes feature no reverse recovery current, temperature-independent switching characteristics, and excellent thermal performance, positioning SiC as the next generation of power semiconductor technology. System-level benefits include higher efficiency, faster operating frequency, increased power density, reduced EMI, and reduced overall system size and cost compared to using an equivalent silicon fast-recovery or ultrafast diode.
