Brief Note on SS14 Diode

The cathode terminal can be identified by using the color band. The marking details on the actual diode is shown below

SS14 Marking Diagram

 

In our case the diode will have SS14 written on top of it. 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 SS14 diode is 0.5V. SS14 diode has a guard ring structure across the metal-semiconductor junction for stress protection.

Characteristics Graph for SS14

 

As shown in the graph the SS14 Diode has a minimum voltage drop of around 0.2V across it when 0.1A is flowing through it, as the current increases the Voltage drop across the diode also increases. The maximum current through the diode is 1A during when then voltage drop is only 0.5V.The maximum reverse voltage is 40V. It can also handle a maximum surge of 30A. 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
