The SF31 thru SF38 series are Super Fast Rectifiers designed for high-efficiency switching applications. These rectifiers offer a reverse voltage range from 50 to 600 Volts and a forward current of 3.0 Amperes. Key features include super fast switching for improved efficiency, low reverse leakage, and high forward surge current capability. They are suitable for applications requiring fast response times and high reliability, with a high temperature soldering guarantee.
