Technical Specifications

The YG911S3 features a maximum repetitive peak reverse voltage (VRRM) of 30V and a maximum average forward rectified current (IF(AV)) of 9A. The forward voltage drop (VF) is typically 0.5V at 9A. The peak surge current (IFSM) is 150A. The operating junction temperature range is -40°C to +175°C. The reverse recovery time (trr) is very fast. It's usually packaged in a TO-252. This diode can be used with high reverse voltages.

This Schottky barrier diode is ideally suited for applications where high efficiency and fast switching are crucial. The low forward voltage drop minimizes power dissipation, resulting in cooler operation and higher overall system efficiency. The high surge current capability ensures that the device can withstand transient current spikes without damage. The fast switching speed allows for higher frequency operation, which can lead to smaller and more efficient power converters. The high operating temperature makes it suitable for demanding applications where heat dissipation is a concern. Its small packaging enables designers to have freedom on their boards. The robust design and Fuji Electric's quality standards provide for a reliable product.
