STPS30170DJF
Power Schottky rectifier
Features
■Very small conduction losses
■Negligible switching losses
■Extremely fast switching
■Low thermal resistance
■Avalanche capability specified
■ECOPACK®2 compliant component
Description
This Schottky rectifier is designed for switch mode power supply and high frequency DC to DC converters.
Packaged in PowerFLAT™, this device is intended for use in low voltage, high frequency inverters, free-wheeling and polarity protection applications.
Its low profile was especially designed to be used in applications with space-saving constraints.

To evaluate the conduction losses use the following equation:
P = 0.65 x IF(AV) + 0.0046 IF2(RMS)
