TVS stands for Transient Voltage Suppressors, diodes devices that are connected as a pair and protect circuits from high voltage electric transients and are available in a diverse range of sizes, configurations and capabilities.

The SMF78A is a highly reliable and versatile TVS-Diode that provides superior protection against transient voltages for a wide range of applications. The diode is composed of two semiconductor junctions that are arranged to create a pn-diode pair which is reverse biased when installed. When transient voltage exceeds the breakdown voltage of the diode, a current flows through the component and the junctions become semi-conductive, allowing surge current to flow. This creates a shunt path to the power supply ground, providing effective protection against transient voltage.

The SMF78A has a working voltage of between 6V and 10V and can dissipate up to 500 watts of peak power. It is suitable for use in a variety of fields, such as consumer electronics, telecom and automotive, where transient protection is needed. It is highly reliable, with a maximum temperature range of between -10°C and +125°C, and its low clamping voltage ensures that it will not damage sensitive components.

The SMF78A offers superior protection for a wide range of applications, such as the protection of LCD displays, audio equipment, LED lighting, junction boxes, etc. In addition, it is capable of providing reverse polarity protection, which is crucial for automotive applications. The reverse polarity protection ensures that the device will not be affected by a reverse polarization of the power supply, thus preventing any possible damage from occurring.

The SMF78A is a versatile device that can be used in a variety of fields where transient voltage protection is necessary. It is highly reliable, and its low clamping voltage ensures that it will not damage sensitive components. Its reverse polarity protection ensures that it will continue to provide effective protection even in cases of a reverse polarization of the power supply. The SMF78A is therefore an ideal choice for applications requiring reliable and effective protection from transient voltage.
