TVS (Transient Voltage Suppressors,) – Diodes are vital components of electronic circuitry devices due to their ability to protect other components from unexpected bursts of voltage or current. With its rapid response time and low clamping voltage, the SLD20U-017-B is a widely used TVS – Diode device with application across many areas.
SLD20U-017-B\'s application field can generally be classified into four main categories:

1. Power Supply Line Surge Protection -

This is the primary application of the SLD20U-017-B, as it is designed to protect power supply lines from unexpected power surges or spikes. The device is installed between the power supply line and the circuit to be protected, and will ensure that power surges or spikes do not cause any damage to the circuitry. The device also has a low “on state” voltage which results in minimal power loss. This is especially useful in larger electronic systems such as Base Transceiver Stations (BTS) and monitoring systems, where power efficiency is a major concern.

2.Automotive Applications -

The SLD20U-017-B is optimally suited for use in automotive applications. It can be used to protect circuit components against alternator spikes and transient voltage surges generated by back EMF from motors or fuel injectors. Additionally, the device helps protect automotive electronics against damage due to environmental stressors such as ESD and EMI.

3.Communication and Wireless Applications -

SLD20U-017-B is also often used for communication and wireless applications. It can be used to protect sensitive circuitry in communication networks and wireless systems, such as Modems, radio transceivers, and satellite receivers. The device also helps protect against lightning strikes and ESD.

4.Consumer Electronics and Industrial Control Applications -

The SLD20U-017-B is a reliable and cost-effective solution for protecting circuit components used in consumer electronics and industrial control applications, such as digital cameras, LCD displays, and computer systems. The absence of a need for external components makes the device an ideal choice, while its low forward on-state voltage and fast response makes it highly efficient in filtering high frequency transients.

Working Principle

The SLD20U-017-B is a voltage-regulation device consisting of a Zener diode connected in series with an unidirectional transient voltage suppressor (TVS). The device offers protection against high-energy transients and voltage surges in excess of the Zener breakdown voltage, diverting most of the surge current around the shunted diode. The device passes normal low voltage/current signals through to the protected device. The entire device is contained in a two-terminal case, making it easy to install and use in electronic circuits.The SLD20U-017-B is designed to operate in a given breakdown voltage range with low clamping voltage and fast response time. It can be used in both AC and DC applications, and offers excellent surge protection for high-impedance logic and interconnect lines in 5V, 12V, and 24V systems. With a low “on-state” voltage of 1.3V (5V), the device is ideal for applications where power efficiency is a concern.

In summary, the SLD20U-017-B is an important component when it comes to surge protection for electronic circuits. The device\'s low clamping voltage, fast response time, and low on-state voltage make it an ideal choice for protection in a variety of applications such as automotive, communication, and consumer electronics, as well as for industrial control, power supply line protection, and wireless systems. By protecting circuitry against unpredictable spikes, the SLD20U-017-B ensures optimal performance and reliability of electronic devices.
