TVS - Diodes

TVS (transient voltage suppressor) diodes are an important part of any electronic circuitry design. These diodes help to protect the circuit from the adverse effects of voltage spikes, electric transients, or ESD (electrostatic discharge) events. The TVS diode, also called a TVS diode or transient voltage suppressor, is a specialized form of diode that is designed specifically to handle large voltage spikes or transients. Transient voltage is a sudden momentary occurrence of high voltage, usually caused by lightning, switching transients, or switching power supply components. TVS diodes can help prevent damage to the components of the electronic circuit.

The PG SMAJ18CAHM2G TVS diode is intended for transient voltage protection and ESD protection. It has a high power rating of 18000 W, and an IEC surge withstand rating of 10A (8/20μs). The PG SMAJ18CAHM2G is also designed with a low leakage characteristic, making it suitable for use in battery powered applications. The maximum peak pulse power is 9500 W, and the voltage range is between 1.5 and 170V.

The working principle of the PG SMAJ18CAHM2G is simple and easy to understand. When voltage spikes or transients occur, the TVS diode "clamps" the voltage to the breakdown level, limiting the damage to the circuit. The diode works by acting as a bidirectional switch, turning on in either direction. When the voltage exceeds the breakdown voltage, current is allowed to flow in one direction, while the other direction is blocked off. This allows the voltage to return to a safe level, while reducing the amount of current and damage to the circuit, protecting the components.

The PG SMAJ18CAHM2G TVS diode is used in a variety of applications. In the automotive industry, it is used in engine computer systems, electrical systems, ignition systems, and ECU control units. It is also used in medical equipment, telecommunications, consumer electronics, military applications, and industrial automation. In addition, it is widely used in power supplies, consumer electronics, and military applications. It is designed to protect sensitive components from voltage spikes and transients, ensuring that the circuitry and components do not fail due to a voltage spike or transient event.

Overall, the PG SMAJ18CAHM2G TVS diode is an essential component of any electronic system. It can help protect sensitive components from transient voltage and ESD events, while providing a low leakage characteristic for battery powered applications. By clamping the voltage to the breakdown level, the diode works to limit the amount of damage to the circuit, while providing reliable protection for the components.
