The SF58G diode is a hyperfast, electrolytically-controlled-rectifier (ECR) manufactured by Yangjie, that is designed for high speed switching applications. It has a reverse avalanche voltage of around 5,800V, and can support max forward current ratings of up to150mA. It operates at a peak reverse-voltage of 5.8V, and a peak forward-voltage of 1.3V. It is packaged in the industry-standard DO-201AD rectifier package, and is RoHS compliant.
