SMAJ100A R3G

TVS diodes are devices that offer protection against over-voltage, power surge and transient voltage surges. The SMAJ100A R3G is a popular Transient Voltage Suppressor (TVS) diode device. It is used in systems and products that require protection against transient voltage spikes.

This diode is made of a material that contains two concentrations of impurities, and can be connected in series with an inductance to provide bidirectional protection. It is very effective in protecting the device under test (DUT) from transient voltage surges. As a TVS diode, this device can handle relatively large voltages and currents, making it suitable for high-voltage and high-current applications.

The SMAJ100A R3G uses a junction termination construction, which increases its reliability. This diode is also an ultrafast device, allowing it to react to voltage spikes in less than 0.2 nanoseconds (ns). The device features a low forward voltage and a low capacitance, optimizing its efficiency and performance in power accuracy.

The SMAJ100A R3G can be used in many different applications. It is commonly used in notebook and laptop computers, LED lighting, automotive applications, and in industrial applications where over-voltage protection is needed. The common device models are most often used in diode or thyristor circuits, and in normal mode operation for unidirectional protection.

The working principle of the SMAJ100A R3G is simple. When a surge of voltage is applied, the diode acts as a switch, conducting current in one direction and blocking in the other. This causes current to flow to the junction between the diode and the inductor, which dissipates the energy created by the surge. The device is designed to conduct the surge and provide protection against voltage spikes over a specified amount of time.

Due to its fast reaction time and reliable protection, the SMAJ100A R3G is one of the most popular TVS diodes on the market. It can be used in a variety of applications to protect your device from sudden voltage surges. When properly used, it can provide reliable protection for your electronics and other sensitive components.
