TVS - Diodes

TVS - Diodes, also known as transient voltage suppressors (TVSs), are semiconductor devices that are used in electronic circuits to protect circuits from potential overvoltage transients.

The 1N8153US is one such device in the family of TVS - Diodes that is widely used for defending sensitive electronic components from unwanted transients through threshold voltages. This diode is a commonly-used component in many systems for the protection of sensitive electronic circuits.

Application Field and Working Principle

The 1N8153US is ideal for use in AC power line transients, automotive and power management applications.The basic principle behind the function of the 1N8153US is the avalanche breakdown voltage. The junction of the diode has a high voltage drop, which causes it to act as a sort of barrier between two terminals. When the voltage on one side reaches the breakdown voltage, the current starts to flow in the reverse direction. This effect is known as avalanche effect or breakdown effect and helps protect sensitive components from transient spikes.

The 1N8153US uses integral junction guarding to improve its performance. This type of protection helps to limit the transient energy passed on to the device. The protection is provided by a single diode in series with a resistor between the junction and the live leads. This type of protection enables the diode to easily switch from its normally blocking state to its conducting state when a voltage transient occurs. The resistor provides an impedance to the circuit to limit the current and protect the components from overvoltage.

The primary uses of the 1N8153US are in automotive applications, power line suppression, and lightning protection. Since the diode can handle high voltage transients, it can be integrated with a surge suppressor for improved protection. This makes it ideal for use in certain automotive systems, such as those used for airbag deployment. It can also be used for power line protection, such as surge suppressors, lightning diverters and overvoltage protectors.

The 1N8153US can also be used for ESD protection. An ESD, or electrostatic discharge, is an abrupt surge in voltage that can cause damage to sensitive electronic components. The 1N8153US can provide a reliable level of protection from ESD events by limiting the amount of current that is passed through it.

Overall, the 1N8153US is a versatile and reliable device for providing protection from overvoltage transients and ESD events. Its ability to handle a high voltage transient makes it suitable for use in many electrical systems, including automotive, power line suppression and lightning protection.
