The SLD18U-017-B is a type of TVS diodes which is typically used for protecting sensitive electronic equipment from voltage spikes. It is widely used in different fields and applications due to its features and properties. This article will discuss the characteristics of the SLD18U-017-B device and its working principle to understand the application field.

Characteristics of the SLD18U-017-B

The SLD18U-017-B is a bi-directional TVS diode which is specifically designed for surge protection for sensitive electronic equipment and systems. The device has a maximum peak power ratings which is 1800 watts (10/1000 µs) for unidirectional and 1750 watts (8/20 µs) for bidirectional. It is capable of handling high levels of transients such as electrostatic discharges (ESD) and lightning surges. It has a high datasheet VBR value which provides a clamping voltage during current spike. It also has a low thermall resistance which allows it to dissipate heat faster and make it highly reliable. The device is available in an SOT23 package or SMB package.

Working Principle

The SLF18U-017-B acts as a surge protection device which suppresses the voltage spikes or transients that occur in the system. It is connected in parallel with the circuitry such that the surge current is redirected away from the sensitive components by passing it through the diode. When a transient occurs, the diode conducts the current away from the sensitive components to provide protection. The device is designed to limit the supply voltage to the specified voltage rating and to protect the system from over-voltage. The device works in coordination with the other components such as capacitors and inductors to provide reducing the peak level of the voltage and clamping the voltage to the specified voltage rating.

Application Field

The SLD18U-017-B is mainly used in applications which require protection from voltage transients like industrial, automotive, consumer electronics and healthcare. It can be used in circuits which require protection from electrostatic discharges, lightning surges and other high voltage transients. The device can be used in Human-Machine-Interfaces (HMIs) such as switches/keyboards, lights, and alarms. It is also suitable for high-frequency data lines, as well as for general-purpose applications, such as Li-ion battery protection, noise voltage generators, etc.

The SLF18U-017-B is an excellent choice for protecting sensitive electronic equipment and systems from voltage transients that may occur in the system. It has a very low thermal resistance which makes it highly reliable compared to other similar devices. It has a high VBR which provides efficient protection against over-voltage and is available in different packages to suite various application needs.
