TVS diodes are components that are designed to provide protection against over-voltage transients in electronic circuits. The SMAJ12HE3/61 is one such Transient Voltage Suppression (TVS) diode designed to protect electrical circuits from a voltage spike.

A voltage spike occurs when the voltage of a circuit suddenly increases to an abnormal level, such as when there is a sudden input of energy to the circuit or when there is a sharp decrease in the load on the circuit. This can cause excessive current to flow through the circuit, leading to damage and possible failure of the circuit. TVS diodes, such as the SMAJ12HE3/61, provide a level of protection from this by diverting the excess voltage away from the rest of the circuit.

The SMAJ12HE3/61 is a unidirectional diode with a 1500W peak pulse power, a 15V working voltage, and a 5V reverse breakdown voltage. These characteristics make it suitable for use in a variety of electrical applications. It has an average current surge rating of 12A for pulses up to 8.3ms and a clamping voltage (VC) of 8.0V. As such, it is well-suited for protecting Ethernet gateways, modems, and other electronic devices from the damage that voltage spikes may cause.

The SMAJ12HE3/61 works by clamping the voltage of the circuit it is connected to when a voltage spike occurs. When the voltage exceeds its breakdown voltage, the diode clamps the voltage to its clamping voltage. This prevents the circuit from experiencing the full effect of the voltage spike, resulting in better protection.

The SMAJ12HE3/61 is an easy to use and cost-effective solution for voltage spike protection. Its simple construction and small size make it an ideal choice for a wide range of applications. It is also RoHS compliant, making it an environmentally-friendly choice for protecting sensitive electronic equipment from the damage caused by voltage spikes.

In summary, the SMAJ12HE3/61 is a TVS diode specifically designed to protect electronic circuits from voltage spikes. It has a peak pulse power of 1500W, a working voltage of 15V, and a reverse breakdown voltage of 5V. It works by clamping the voltage of the circuit to a safe level when a voltage spike occurs, preventing the circuit from experiencing the full effect of the spike and thus providing better protection. The SMAJ12HE3/61 is a simple and cost-effective protection solution, and is suitable for use in a variety of applications.
