TVS or Transient Voltage Suppressors are widely used in both commercial and consumer electronic devices for over-voltage and surge protection. The SMS15T1 is a special type of TVS diode that is specifically designed to help protect common low voltage applications from voltage surges. It is an unidirectional bidirectional diode, meaning that it functions in either direction.

The SMS15T1 can protect loudspeakers, microprocessor circuits, and other sensitive electronic components from damage caused by voltage spikes. It also helps reduce audio distortion caused by static electricity. It is ideal for use in car stereo and audio cassette systems, personal computers, telephone lines, and other similar applications.

A typical SMS15T1 diode consists of two p-type silicon and two n-type silicon semiconductor dies. The two p-type silicon dies are connected in series with the two n-type silicon dies and form the diode. The SMS15T1 is designed to be able to handle up to 600V of reverse breakdown voltage, so it is more than capable of handling the voltages typically found in car stereo systems and personal computers.

When connected in series with the device to be protected, a voltage spike will cause the current to flow in the reverse direction if the voltage exceeds the threshold. The reverse current flow will cause the SMS15T1 diode to conduct and dissipate the electrical energy, thereby protecting the device. The reverse breakdown voltage of the SMS15T1 is typically in the range of 600-700V, providing ample protection against typical voltage spikes.

The SMS15T1 also has a low resistance path to the GND level when it is in the “on” state. This helps prevent the flow of current to other parts of the circuit. The low resistance path ensures that the total load impedance remains low even in the presence of a voltage spike.

In addition to its protective features, the SMS15T1 is also designed to provide a low leakage current when the diode is in its “off” state. This feature ensures that the diode does not draw too much current when inactive, saving power. The SMS15T1 also has a low Capacitance Device characteristic, reducing power dissipation and improving noise immunity. Overall, the SMS15T1 is an ideal choice for low voltage applications that require protection from voltage spikes.
