Diodes are current-controlled devices that allow current to pass through them in one direction, while restricting it from passing through in the other direction. Zener diodes are a specific type of diode that utilizes both the PN junction and avalanched breakdown to create a voltage regulator. The SMBJ5954A/TR13 is a two terminal, single substrate, epitaxially grown Zener diode with a working breakdown voltage of 4.7V.

The SMBJ5954A/TR13 is capable of higher current rates, while dissipating smaller power compared to other Zener diodes with a similar working voltage. The Zener diode features a low reverse leakage current, low noise at high frequencies, and a fast response time. This makes is suitable for a range of applications in the consumer, automotive, industrial, and military markets.

The SMBJ5954A/TR13 device works through the application of the PN junction to the principle of the avalanche breakdown. In simple terms, this means that when a certain amount of reverse-bias voltage is applied to the diode, ‘avalanche multiplication’ of the charge carriers means that, instead of blocking current flow, the diode begins to allow current to pass through. To keep the current at a safe level, diodes like the SMBJ5954A/TR13 incorporate a metal oxide layer which helps funnel the current.

This breakdown voltage means that regardless of the voltage on either side of the diode, it will remain stable at 4.7V. This stability makes it ideal for a range of applications, such as helping to build and maintain a stable voltage level in AC adapters, preventing voltage spikes in automotive circuits, providing decoupled power in power subsystems, and creating highly reliable power distribution networks in industrial settings.

The SMBJ5954A/TR13 uses a two-terminal style consisting of a cathode and an anode. When connected properly to a power source, the anode lead receives charge current and the cathode lead emits charge current. The opposite connections would cause the device to act as an open circuit, preventing current from passing through. The Zener diode is intended for electronic equipment applications and should be kept at a maximum atmospheric temperature of 70°C to ensure optimal performance. Proper application and use of this device is the responsibility of the designer or end user.

In summary, the SMBJ5954A/TR13 is a single substrate, two terminal, Zener diode designed to provide 4.7V breakdown voltage when subjected to a reverse bias voltage. Its low operating resistance and low noise qualities are an ideal combination of characteristics a range of applications ranging from consumer electronics to military equipment. The diode should be protected from environmental temperatures exceeding 70°C in order to ensure accurate regulation and long device reliability.
