TVS (Transient Voltage Suppressor) diode, also known as a Transient Voltage Spike Suppressor, is a semiconductor device used to prevent expensive damage from electrical surges caused by electrostatic discharge (ESD), lightning, and other electromagnetic sources. SM16LC15/TR13 is a particular type of TVS diode with a working principle based on avalanche breakdown.

The SM16LC15/TR13 is made from substrate materials such as Silicon, Germanium, and Silicon Carbide. It is designed to handle up to 25 Amps continuous low level surge pulse current, with a breakdown voltage of up to 900Volts. This device is widely used to protect sensitive electronics circuits from ESD and other forms of transient voltage spike.

The SM16LC15/TR13 works by using the principle of avalanche breakdown. This process occurs when the potential applied across the device exceeds a critical value. At this point, the electrons in the diode are accelerated to a speed greater than the thermal velocity of the material. These fast-moving electrons collide with atoms in the semiconductor creating additional charge carriers that cause current to flow in the opposing direction.

The SM16LC15/TR13 is a bidirectional device, typically used in a back-to-back configuration. This means that two diodes are connected in such a way that current can flow in either direction. The two diodes are configured to clamp any voltage higher than the breakdown voltage of the individual diodes. As a result, any ESD or transient pulses that occur in the circuit will be safely absorbed by the device.

The SM16LC15/TR13 has wide application range, including consumer electronics, telecommunications, automotive, and industrial equipment. It is commonly found in applications such as on-board computers, industrial controls, robotic arms, power supplies, and many other electronic devices. This device is an excellent choice for protecting sensitive electronics from transient pulses caused by ESD, lightning, and other sources.

In conclusion, the SM16LC15/TR13 is a type of TVS diode used to protect electronics circuits from transient voltage spikes due to ESD, lightning, and other sources. This device works by using the principle of avalanche breakdown, a phenomenon in which electrons are accelerated beyond their thermal velocity to create a “avalanche” of current. The SM16LC15/TR13 is a widely used device that can be found in a variety of electronics applications.
