Diodes - Zener - Single: SMBJ5930A/TR13 Application Field and Working Principle

Zener diodes, named after Claude Zener, are type of diodes whose purpose is to maintain a specific voltage across its terminals. They are widely used to regulate power supply or to protect computers and circuit boards from excessive voltage. The SMBJ5930A/TR13 is a single Zener diode made in the glass-passivated junction diode form.

Application Field:
SMBJ5930A/TR13 Zener diodes are widely used in voltage-regulator circuits, voltage-suppressor circuits, DC power supply circuits, clamp circuits, LED driver circuits, and other low-voltage circuits. They are also suitable for switching applications, such as radio frequency identification (RFID) communication, wireless LAN systems, and alarm systems in cars. Power line communication, home security systems, and distributed power system communications are also suitable applications.

Working Principle:
SMBJ5930A/TR13 Zener diodes operate by allowing current to flow from the anode to the cathode when the voltage across it is higher than the breakdown or Zener voltage at which it is designed to operate. This voltage is usually between +2.2 V and +56 V. Zener breakdown occurs when electrons in the junction region gain enough energy to overcome the barrier of the depletion region, which then allows a large number of carriers to flow through the junction. This causes a sudden increase in the current flow, thus forming a conducting path. The SMBJ5930A/TR13 features a reverse breakdown voltage ranging from +2.2 V to +56 V, with a maximum reverse current rating of 95.

Zener diodes are useful in that they can be used to protect against overvoltage, undervoltage, and transients. The SMBJ5930A/TR13 is a versatile diode for use in many applications. It is robust and easy to install, and the wide range of breakdown voltages makes it well suited for many applications. Its glass-passivated junction makes it suitable for high-temperature and harsh-environment conditions.

Overall, the SMBJ5930A/TR13 is a single Zener diode suitable for applications in voltage regulation, voltage suppression, DC power supply, and other low-voltage applications. It is reliable, robust, and features a wide range of breakdown voltages, making it a versatile choice for many applications.
