Working Principle
The SMBJ5364AE3/TR13 diode works according to the principle of the Zener Breakdown. This concept describes the behavior of a diode when it is exposed to a reverse bias voltage, which is beyond its breakdown voltage. When this voltage is reached, the diode allows the current to flow from its reverse-connected anode to its cathode while the voltage remains constant and stable. This voltage is known as the Zener voltage and it is indicated by the “Vz” marking on the diode.
When this diode is forward-biased and the forward current exceeds its maximum forward current rating, the diode will limit the current flow and the voltage drop across the diode will rise to the rated forward voltage. In this mode, the diode behaves as a normal rectifying diode.
In addition, this diode has a very low temperature coefficient, which means that its breakdown voltage remains almost the same over a broad temperature range – from -55°C to +125°C. This feature makes the SMBJ5364AE3/TR13 diode suitable for use in a wide range of industrial applications.
