SS310 Diode Overview

A diode is a device which allows current flow through only one direction. That is the current should always flow from the Anode to cathode. The cathode terminal can be identified by using the color band. The marking details on the actual diode is shown below

Compared to normal diodes Schottky diode also has relatively faster switching speeds and hence can be used in high-frequency switching circuits. It also has low forward drop voltage, the voltage drop across the SS310 diode is 0.85V.

SS310 Schottky Diode Characteristic Graph

 

As shown in the graph the Diode has a minimum voltage drop of 0.4V across it when 0.1A is flowing through it, as the current increases the Voltage drop across the diode also increase. The maximum current through the diode is 3A and the maximum reverse voltage is 100V. It can also handle a maximum surge of 80A. The complete details of the diode can be found at the datasheet below.

 

Applications of Diode

  • Can be used to prevent reverse polarity problem
  • High-Frequency Inverters
  • Used as a protection device
  • Current flow regulators
  • Polarity Protection applications
