SI4477DY Description

Short technical summary and product information.

The Vishay Dale SI4477DY is a P-Channel Power MOSFET designed for applications such as load switching and adapter switching, commonly found in notebooks and game stations. It offers a drain-source voltage (Vds) of -20V and a gate-source voltage (Vgs) of ±12V.

 

Key electrical characteristics include a low drain-source on-state resistance (Rds(on)) of 0.0062Ω at VGS = -4.5V and ID = -18A, and 0.0105Ω at VGS = -2.5V and ID = -14A. The continuous drain current (ID) is rated up to -26.6A at TC = 25°C. It also features a typical forward transconductance (gfs) of 10S.

 

This MOSFET is housed in a SO-8 package and is surface mountable. It operates within a junction temperature range of -55°C to 150°C. The device is compliant with RoHS Directive 2002/95/EC and is halogen-free according to IEC 61249-2-21 definition.
