United Silicon Carbide, Inc. offers the 3rd generation of high
performance SiC Merged-PiN-Schottky (MPS) diodes. With zero reverse
recovery charge and 175°C maximum junction temperature, these
diodes are ideally suited for high frequency and high efficiency power
systems with minimum cooling requirements.
Repetitive peak reverse voltage, Tj=25°C
Extremely fast switching not dependent on temperature
No reverse or forward recovery
Enhanced surge current capability, MPS structure
175°C maximum operating junction temperature
Excellent thermal performance, Ag sintered
Maximum DC forward current
Non-repetitive forward surge current
