TVS-Diodes

TVS-Diodes (transient voltage suppressors) are solid-state devices composed of two separate diodes electrically connected together that are designed to protect sensitive electronic parts and equipment from any sudden, extreme hike in voltage or surge. There are several different types of TVS-diodes on the market today, each designed to protect a certain range of voltages and respond to various surge durations. One such type of TVS-diode is the TV02W220B-HF.

TV02W220B-HF

The TV02W220B-HF is a unidirectional, two terminal device designed for use in response to lightning and other high-energy, short-duration events. It accepts voltages of up to 220V and is designed to divert the voltage away from sensitive components in order to avoid any damage. The device requires minimal de-rating at elevated temperatures, so it is suitable for a wide range of applications where temperature control is not feasible.

Application Field

The TV02W220B-HF is designed for a wide range of applications where protection against high-energy, short-duration events is a priority, such as telecommunication and industrial equipment. It is also ideal for a variety of other applications, such as consumer electronics, automotive electronics, and appliances. The TV02W220B-HF is perfect for applications that require a high level of surge protection but are unable to accommodate large, bulky TVS-diodes, or require temperature control.

Working Principle

The TV02W220B-HF is designed to respond quickly to a surge in voltage by diverting the voltage away from the component or equipment that is being protected. This is done by utilizing a thyristor, which is a four-layer semiconductor that is composed of two p-type and two n-type materials. During a surge in voltage, the device is triggered and turns on, redirecting the over-voltage away from the protected component or equipment. The device utilizes the silicon surge absorption principle to protect sensitive components from damage in the event of an over-voltage surge. When triggered by an over-voltage, the silicon avalanche breakdown principle is triggered, and the diode begins to divert the voltage away from the sensitive component. The silicon avalanche breakdown principle works by inducing a Zener breakdown effect in the junction of the two diodes in the TV02W220B-HF. This induces a rapid large-signal response, allowing the protected components to remain safe from any external voltage surges.

Conclusion

The TV02W220B-HF is a great choice for applications where protection against high-energy, short-duration events is needed and temperature control is not feasible. The device utilizes the silicon surge absorption principle to divert voltage away from sensitive components, and is perfect for a variety of different applications ranging from telecommunication and industrial equipment to consumer electronics and automotive electronics.
