This type of diode is used in a variety of applications, including voltage regulators, current limiting diodes, voltage clamps, crowbar and transient protection circuits. It is also used in SMPS (Switch Mode Power Supplies), and other switch-mode power supplies, discontinuous conduction mode (DCM) AC/DC converters, power factor correction and high-side switches. It is also used for general purpose protection and as a rectifier diode. It can be used in a variety of other applications such as color television sets, instrumentation and other voltage sensitive circuits and systems.

Working Principle

SMBG5364AE3/TR13 diodes operate according to the Zener effect. When a high electric field is applied across a semiconductor junction, the electrons are attracted to the high potential side, creating a charge imbalance and resulting in the Zener breakdown voltage. The Zener breakdown voltage of the SMBG5364AE3/TR13 is around 6.2V. When the forward bias voltage applied across the diode reaches this breakdown voltage, the current flows freely in a reverse direction, instead of increasing as it would in a normal forward-biased diode.

At voltages below the breakdown voltage, the SMBG5364AE3/TR13 can be used as a normal diode and will act as a rectifier. The diode will impede reverse currents, providing the necessary voltage and current regulation the circuit needs. When the forward current is too high, the reverse current will be forced away, protecting the circuit from an over-current.

At voltages above the breakdown voltage, the reverse current of the SMBG5364AE3/TR13 will start to increase exponentially as the voltage continues to rise. It is important to note that the breakdown voltage of the diode should not be exceeded, as it can lead to permanent damage and reduce the lifetime of the diode drastically.

Conclusion

SMBG5364AE3/TR13 is a single Zener diode designed to operate according to the Zener effect. This type of diode can be used in a variety of applications, including voltage regulators, current limiting diodes, voltage clamps, crowbar and transient protection circuits, as well as general purpose protection and as a rectifier diode. It is important to note that the breakdown voltage should not be exceeded, as it can lead to permanent damage and reduce the diode’s lifetime.
