Description

The STTH8BC065 is a specific rectification diode
used in continuous mode power factor correction
working in the BC
especially designed for the dedicated BC
topology. Therefore, its electrical characteristics
offer the best possible efficiency with a P-N
optimized structured diode. As a result, SMPS
efficiency growth of up to 2.5% can be produced
compared with standard ultrafast 600 V P-N
diode.
