Working Principle

The 1PMT5955C/TR13 Zener diode operates according to the principle of electrical breakdown. This occurs when the electric field strength in a reverse-biased diode is strong enough to allow carriers (electrons and holes) to be accelerated across the potential barrier formed by the junction PN. As a result, current starts to flow in the reverse direction, creating a characteristic Voltage-Current (V-I) or Zener curve.

During regular operation in a forward-biased direction (the diode acts as a regular diode), the device allows very low levels of Reverse Current (IR). This is due to the low breakdown voltage and the very high quality of the PN junction. When the voltage is increased, the Zener diode reaches its breakdown point, at which the breakdown current starts to flow. This ensures a very high level of control over the output voltage.

Package

The 1PMT5955C/TR13 comes in an SOD-523 package with a maximum temperature of 150°C making it ideal for high-temperature environments. It is designed to be used in a wide range of industrial, automotive, communications and computer applications.
