The IRF9640TU(SAM) is a Surface-Mounted Schottky Rectifier Diode manufactured by Samsung Electronics. This diode is used to control the flow of current in an electrical circuit. It can withstand up to a peak repetitive reverse voltage of 60 volts (VRRM) and has an average forward current rating of 3.0 amperes (IF(AV)). The IRF9640TU(SAM) features very low forward voltage drop and low forward leakage current. It is typically used for switching, rectification, and protection applications such as in automotive, computer, telecom, and consumer electronics equipment.
