TVS - Diodes

TVS diodes, also known as Transient Voltage Suppression diodes, are designed to protect sensitive electronic components from damage due to voltage spikes and surges. These devices are categorized as bi-directional or unidirectional, depending on the design of the silicon crystal inside. Unidirectional diodes will protect from high-voltage spikes coming from one side of the diode’s terminals, but not from spikes on the other side. Bi-directional TVS diodes protect from both types of electrical transients.

The SMBJ5V0A is one of the most popular bi-directional TVS devices on the market. This device is designed to protect sensitive electronics from transients and power surge voltages of 5V peak, with a breakdown voltage of 5.6V. It is made of a two-layer construction, with a silicon diode sandwiched between two layers of ceramic material. This helps minimize the stress applied to the internal elements and allows the device to tolerate higher voltage spikes than unidirectional TVS devices. The SMBJ5V0A also has an on-state resistance of 0.15Ω, preventing it from accumulating too much current in case of prolonged surge times.

SMBJ5V0A devices are commonly used in many types of electronic circuits, ranging from low-end consumer electronics to industrial machinery. For consumer electronics, they are used to protect logic circuits and critical components from damage due to voltage surges from the AC power lines. They are also used in industrial machinery to protect against lightning strikes or other sources of high-voltage transients. In addition, these devices are also useful in the automotive industry to protect control systems from voltage transients from the engine’s power supply.

The working principle of TVS devices is simple. When a voltage spike or surge is applied to the device, the internal diode begins to conduct current. This increases the voltage across the device, which causes its internal element to break down and dissipate the energy of the transient. As a result, current is prevented from flowing into sensitive components that could be damaged by a surge, allowing the circuits to remain functional.

In conclusion, the SMBJ5V0A is a popular bi-directional TVS device used in many applications. It is designed to protect sensitive electronic components from damage due to voltage spikes and surges. Its two-layer construction allows it to tolerate higher voltage spikes, and its on-state resistance prevents it from accumulating too much current. The working principle of the device is simple: when transients are applied to it, its internal element breaks down and dissipates the energy, thus preventing electrical damage.
