AEC-Q101 approved devices with 120V, 150V, and 200V combine best attributes of Schottky and fast recovery diodes
Nexperia, the expert in essential semiconductors, has announced a range of new silicongermanium (SiGe) rectifiers with120 V, 150 V, and 200 V reverse voltagesthat combine the high efficiency of their Schottky counterparts with the thermal stability of fast recovery diodes.
Targeting automotive, communications infrastructure and server markets, the new 1-3 A SiGe rectifiers are of particular benefit in high-temperature applications like LED lighting, engine control units or fuel injection. Design engineers using the new, extremely low leakage devices can now rely on an extended safe-operating area with no thermal runaway up to 175 degrees. At the same time, they can optimize their design for higher efficiency whichis not feasible using fast recovery diodescommonly used in such hightemperature designs.By boosting a low forward voltage (Vf)and low Qrr, the SiGe rectifiers have an advantage of 10-20% lower conduction losses.
The PMEG SiGe devices (PMEGxGxELR/P) are housed in size- and thermally-efficient CFP3 and CFP5 packages that have become the industry standard for power diodes. By featuring a solid copper clip the packages’ thermal resistance is reduced and transfer of heat into the ambient environment is optimized, allowing small and compact PCB designs. Moreover, simple pin-to-pin replacements of Schottky and fast recovery diodes are possible when switching to SiGe technology.
Jan Fischer, Nexperia product manager commented: “UtilisingNexperia’sinnovative Silicon Germanium technology gives engineers unprecedented options to design their power circuitry and finally build market-leading products. SiGeperfectly complements Nexperia’s power diodes offering which includes more than 100Schottky and fast recoveryrectifiers in the clip-bonded FlatPower (CFP) package. And, we continue to grow this portfolio to always offer our customers a part which is the ideal fit for their application.”
The first four AEC-Q101-qualified 120 V SiGe rectifiers are already in mass production. A further eight 150 V and 200 V devices are sampling now.
