ONSEMI S1G Standard Recovery Diode, 400V 1A, SMA Package

The ONSEMI S1G Standard Recovery Diode is a high-performance, glass passivated general-purpose rectifier, engineered for optimal electrical characteristics. It features a notably low leakage current, minimal capacitance, and a fast response time, making it an efficient choice for a wide range of power management circuits. A colour band on the body clearly denotes the cathode end for easy and correct polarity identification during installation.

This robust component is designed for general use and is suitable for many different electronic applications. With a power dissipation of 1.4W and a typical total capacitance of just 6.6pF (measured at 4V/1MHz), it offers reliable performance in switching and rectification roles. The diode is housed in a compact DO-214AC (SMA) package, a popular surface-mount style that saves valuable board space.
