TVS - Diodes

Category Introduction

TVS Diodes are a semiconductor device designed to limit or stop surges in a specific voltage level. The items in this family are designed using diodes (a component that conducts in just one direction). TVS is an acronym for Transient Voltage Suppression (Suppressor). The types are steering (rail to rail) or Zener with the characteristics of unidirectional channels, bidirectional channels, voltage – reverse standoff, voltage – breakdown, voltage – clamping, current – peak pulse, power – peak pulse, and power line protection.

About TVS Diodes

What are TVS Diodes?

TVS Diodes

TVS Diodes, or Transient Voltage Suppressor Diodes, are semiconductor devices designed to protect electronic circuits from voltage spikes. These spikes, often caused by lightning strikes, electrostatic discharge (ESD), or inductive load switching, can damage sensitive components. TVS Diodes operate by clamping the voltage to a safe level, effectively absorbing the excess energy and preventing it from reaching the protected circuit. They achieve this through their ability to switch from a high-impedance state to a low-impedance state when the voltage exceeds a certain threshold, thus diverting the surge current away from the protected components.

Types of TVS Diodes

Unidirectional TVS Diodes

Unidirectional TVS Diodes are designed to protect circuits from positive voltage transients. They are ideal for DC applications where the voltage polarity is consistent. These diodes are commonly used in power supply lines and DC power rails, where they provide robust protection against overvoltage conditions.

Bidirectional TVS Diodes

Bidirectional TVS Diodes offer protection against both positive and negative voltage transients. They are suitable for AC applications or circuits where the voltage polarity can change. These diodes are often used in data lines and communication interfaces, providing comprehensive protection in environments where polarity reversal is possible.

Array TVS Diodes

Array TVS Diodes consist of multiple diodes integrated into a single package, offering protection for multiple lines or channels. They are particularly useful in applications like USB ports, HDMI interfaces, and other multi-line data transmission systems, where space-saving and efficient protection are critical.

How to choose TVS Diodes?

When selecting TVS Diodes, several key parameters must be considered:

Breakdown Voltage (V_BR): Choose a diode with a breakdown voltage slightly above the normal operating voltage of the circuit to ensure effective protection without interfering with normal operation.
Clamping Voltage (V_CL): Ensure the clamping voltage is below the damage threshold of the protected components.
Peak Pulse Power (P_PP): Select a diode capable of handling the maximum expected surge current.
Response Time: Opt for diodes with fast response times to ensure immediate protection against transients.

Evaluating product quality and reliability involves reviewing supplier certifications, customer reviews, and testing data. Consider environmental factors such as temperature range and humidity, and ensure the diode is compatible with the installation requirements, such as mounting style and package size.

Applications of TVS Diodes

Automotive Industry

In the automotive sector, TVS Diodes protect sensitive electronic systems such as engine control units (ECUs), infotainment systems, and sensors from voltage spikes caused by load dumps and inductive switching. They ensure the reliability and longevity of automotive electronics in harsh environments.

Telecommunications

TVS Diodes are crucial in telecommunications for safeguarding network equipment, such as routers and switches, from ESD and lightning-induced surges. They maintain the integrity of data transmission and prevent downtime in communication networks.

Consumer Electronics

In consumer electronics, TVS Diodes protect devices like smartphones, tablets, and laptops from ESD and power surges. They help maintain device performance and prevent costly repairs or replacements due to electrical damage.

Industrial Equipment

Industrial applications utilize TVS Diodes to protect machinery and control systems from voltage transients caused by switching operations and lightning strikes. They ensure the safe and efficient operation of industrial processes.

Medical Devices

In the medical field, TVS Diodes protect sensitive diagnostic and monitoring equipment from electrical surges, ensuring accurate readings and the safety of both patients and healthcare providers.
