Surge current is one of the most destructive elements in electrical systems. Transient voltage suppressors (TVS) diodes are designed to protect sensitive circuits against voltage transients. Applications such as laptop computers, digital cameras, and mobile phone chargers could benefit greatly from these devices. The SMAJ160CA R3G TVS Diode is one such solution.

The SMAJ160CA R3G is a 500W unidirectional diode designed to protect circuits from excessive voltage transients. This transient voltage suppression device rated for 600W peak power pulses per line and 600W peak on the junction at 25°C. It has a breakdown $\textit{voltage}$ of 25V and an operating $\textit{temperature}$ range of -55°C to 150°C. It is designed to protect circuits from over-voltage transient events, such as electrostatic discharge (ESD) and lightning strikes, and can also protect from electrical surges in data and signal lines.

However, it is important to note that the SMAJ160CA R3G is not suitable for use in power and high current applications, and should only be used in low current, low voltage applications. It is also important to get the right TVS diode for your particular application, as different TVS diodes are designed for different voltage ranges.

The working principle of the SMAJ160CA R3G TVS diode is based on the avalanche effect. This effect occurs when electric current is passed through a material in a reverse direction, causing the electrons to rapidly gain energy, and thus tunnel through the bandgap of the material. This tunneling of the electrons results in a large increase in current, which is the basis of the avalanche effect. The avalanche effect is used in the SMAJ160CA R3G, as it allows the diode to rapidly suppress voltage transients.

The diode is designed so that when a voltage transient is detected, the electrons tunnel through the bandgap, which causes the voltage spike to be rapidly suppressed. The SMAJ160CA R3G is designed to protect against voltage transients up to 600W, while also maintaining a low on-state resistance of 1.7 ohms. This allows for higher surge and lightning current protection, while also providing low voltage drop across the diode.

The SMAJ160CA R3G TVS diode can be a great tool for protecting circuits from voltage transients and surges. It is designed for low current, low voltage applications, and is rated for 600W peak power pulses per line and 600W peak on the junction at 25°C. It features a low on-state resistance of 1.7 ohms and a breakdown voltage of 25V. The working principle of the SMAJ160CA R3G is based on the avalanche effect, which allows it to rapidly suppress voltage transients.
