Nexperia Silicon Germanium (SiGe) Rectifiers
Nexperia Silicon Germanium (SiGe) Rectifiers combine the efficiency of Schottky rectifiers with the thermal stability of fast recovery diodes, enabling engineers to optimize the 120V to 200V power designs for higher efficiency. These AEC-Q101-compliant SiGe rectifiers offer an extended safe operating area with no thermal runaway up to +175°C, making these Nexperia rectifiers ideal for high ambient temperature applications. The SiGe Rectifiers are housed in Clip-Bonded FlatPower (CFP) packages, which feature a solid copper clip for high thermal performance and power dissipation.
