Additional Details:

The US1MS has a maximum repetitive peak reverse voltage (VRRM) of 600V and a maximum average forward rectified current (IF(AV)) of 1A. It features an ultrafast reverse recovery time (trr) typically around 75ns. The device is available in a DO-214AC (SMA) package. It is designed to operate over a wide temperature range, typically from -65°C to +175°C. The low forward voltage drop minimizes power dissipation and increases efficiency. The high surge current capability ensures that the rectifier can withstand transient current surges without failure. Its compact size makes it suitable for applications where space is limited. It is RoHS compliant.
