FERD20L60C
60 V field-effect rectifier diode
Datasheet - production data
Features
ST advanced rectifier process
Stable leakage current over reverse voltage
Reduced leakage current
Low forward voltage drop
High frequency operation
Description
The device is based on a proprietary technology
that achieves the best in class VF/IR trade-off for a
given silicon surface.
This 60 V rectifier has been optimized for use in
confined applications where both efficiency and
thermal performance are key.
This device is suitable for use in adapters and
chargers.
