TVS diodes provide one with an effective solution to prevent the damage done by electrostatic discharges, commonly referred to as Electric Over Stress (EOS). The SMA18AT3G TVS diode, a 600W silicon transient voltage suppression diode, is a typical example of such a device. The SMA18AT3G is able to absorb transients up to 600 Volts, making it a versatile, reliable and cost-effective defense against electrical overstress on your circuit.

The transient voltage suppression diode works on a very simple principle. It consists of a PN junction diode, connected in parallel across the input side of the circuit which is being protected. When the voltage of the circuit rises to a peak of over the breakdown voltage of the diode, the diode gets momentarily switched on and clamps the voltage to within a safe region, thus protecting the components of the circuit from any overvoltage. Any remaining overvoltage is then suppressed as long as the transient stays within range.

Application fields of the SMA18AT3G diode cover a wide array of systems, from mobile phone chargers, notebook PC and battery packs to direct wall plug in chargers. It is installed in a variety of consumer electronics and security systems due to its more than satisfactory performance.

The SMA18AT3G diode also finds use in systems with short-circuit protected fuses, which use sensitive current fuses. These fuses can ensure a good protection with over current spike clamping, but they become useless in the case of low current ground loop overstress. In such cases, the addition of the SMA18AT3G diode to the circuit can provide an effective secondary circuit protection.

The SMA18AT3G diode contributes to the reliability of the system by preventing any false triggering or damage resulting from transients and overvoltage. The integrated protection steps in to help bridge the tiny but crucial gap between normal operation and destruction.

Overall, the SMA18AT3G TVS diode provides an attractive package of cost effective solution with reliable ESD protection in a wide variety of consumer electronics and industrial devices. Installing this device will ensure that your system is safe from any sort of transient voltages, thus preventing any fatalities from accidental electric overstress.
