SLD17-018

TVS - Diodes

In electronics, a Transient Voltage Suppressor (TVS) diode, also known as a Transient Voltage Suppression diode, is a special type of diode designed to protect electrical equipment from high-voltage transients, such as those induced by lightning surges. The SLD17-018 is a dual channel TVS diode with an operating field of 18 volts.

The SLD17-018 has two main functions, one is to protect equipment from over-voltage and another is to protect from electrostatic discharge (ESD). SLD17-018 is able to absorb voltages up to 18 volts. Under normal circumstances, the voltage is constrained within the operating range, but if the voltage should happen to go above this range for whatever reason, then the SLD17-018 will act to suppress the voltage. This helps to prevent any possible damage to the equipment.

The working principle of the SLD17-018 is quite simple. When a voltage is applied to the TVS diode, the diode begins to restrict the current, or voltage, flowing through it. When the voltage reaches the predefined clamping voltage of the diode, typically around 18 volts for SLD17-018, the diode starts clamping the voltage, thus protecting the device downstream from any over-voltage which could cause damage. Once the voltage drops below the clamping voltage, the diode will restore the flow back to normal.

The basic components that make up a TVS diode include a resistor, a semiconductor substrate, and a zener diode. The semiconductor substrate is typically made of silicon, but other materials such as gallium arsenide can also be used. The diode is used to regulate and redirect the voltage while dissipating excess power as heat. The resistor is used to dampen the voltage and prevent it from spiking too high; this also helps protect the components downstream from the diode from over-voltage.

The SLD17-018 is a useful tool for a variety of electronics applications. For example, it can be used to protect electric motors from lightning surges, as well as to protect electronic devices from ESD, preventing them from damage. It can also be used to protect circuitry in automobiles, consumer electronics, and many industrial and medical applications.

In summary, the SLD17-018 is a dual channel TVS diode designed for protection against over-voltages. The diode works by clamping the voltage when it exceeds predefined levels, and by dissipating excess power as heat. It is a useful tool in a variety of applications, including automotive, consumer electronics, motor control, and many more.
