FERD30SM100DJF
Fi eld ef fect rectifi er
Datasheet − production data
Features
•ST proprietary process
•Reduce leakage current
•Low forward voltage drop
•High freque ncy operation
•ECOPACK®2 compliant component
Description
The FERD30SM100DJF is based on a proprietary
technology that achieves the best in class VF/IR
trade-off for a given silicon surface.
This 100 V rectifier has been optimized for use in
confined applications where both efficiency and
thermal performance are k ey.
