Features
• ST patented rectifier process
• Stable leakage current over reverse voltage
• Low forward voltage drop
• High frequency operation
• ECOPACK ® 2 compliant
Applications
• Adapter
• Gaming console power supply
• Battery charger
• DC / DC converter
Description
This single rectifier is based on a proprietary technology, enabling to achieve the best in class V
F
/I
R
for a given silicon surface.
Packaged in TO-220AB, TO-220FPAB and D 2 PAK, the FERD40H100S is optimized for use in confined applications where both efficiency and thermal performance are key. With a lower dependency of leakage current (I
R
) and forward voltage (V
F
) in function of temperature, the thermal runaway risk is reduced. It is highly recommended to be used in adapters and chargers.
