Description
The STTH3BCF060 is a specific freewheel diode
used in continuous mode power factor correction
working in the BC² topology. This diode has been
especially designed for the dedicated BC²
topology. Therefore, its electrical characteristics
offer the best possible efficiency with a P-N
optimized structured diode. As a result, SMPS
efficiency growth up to 2.5% can be produced at
an optimized cost.
