The SMF30A is an Bidirectional Transient Voltage Suppressor (TVS) diode manufactured by SOCAY. It is a metal surface-mount, bi-directional device, designed to protect voltage sensitive components from electrostatic discharge (ESD) and electrical overstress (EOS) typically caused from lighting, inductive switching and other electrical effects. It is encapsulated in a SOD-123 package and has a breakdown voltage of 48.4V, an ESD protection voltage of 33.3V, and a steady-state voltage of 30V, all compliant with the EU RoHS standard. The device is suitable for use in a variety of applications, including automotive, industrial, consumer, and telecommunications.
