TVS - Diodes

TVS-Diodes, also known as Transient Voltage Suppressors(TVSs), are unpolarized semiconductor devices designed to protect against transient excessive voltage events. They are commonly specified to reduce potential damage to electrical and electronic components from lightning and electrical surge events. Capable of handling ESD, EFT or surge voltages beyond the capabilities of other passive discrete components, they are used in a variety of consumer and industrial products. The 5KP64-B is one of these TVS-diodes and we will discuss its application field and working principle here.

Application Field

The 5KP64-B is most commonly used in computers, hardwire and all kinds of electronic equipment. It\'s designed to protect against damage from transients caused by overvoltage events such as lightning strike or electrostatic discharge. It can also be used in various types of electrical equipments such as power supplies, switches, motors and connectors.

It\'s also used in electrical circuits where high voltage noise malfunctions are expected from lightning strikes or power line problems. The breakdown voltage of the 5KP64-B is 64 Volts, which makes it ideal for transient voltages up to that level. It\'s suitable for all types of AC/DC applications, comes in a 5mm square DO-15 package and is compatible with most electrical insulation materials.

Due to its extremely quick response time, low tunneling capability and low operating power, the 5KP64-B is ideal for high speed operation. It\'s highly reliable and does not require any additional components for installation. Additionally, it is economical and operationally compatible with all current conduction components. The 5KP64-B is a reliable way to protect against transient voltage blasts.

Working Principle

TVS-Diodes work on the principle of basic diode operation. When overvoltage is applied to the diode, it goes into avalanche breakdown which is a process of accelerated heating of electrons. This increases the current flow which triggers the breakdown voltage, causing the diode to conduct. The 5KP64-B can also be used in a reversed configuration, which further decreases the voltage across the diode.

The diode has a flat characteristic curve such that any voltage applied will increase the current in a linear fashion. This helps protect against high energy spikes that could cause permanent damage to components. In the case of the 5KP64-B, it will conduct any voltage above 64V, diverting the energy away from the equipment.

In order to function, the 5KP64-B should be connected with a resistor. The circuit should then be connected to the ground. The resistor determines the amount of current that will be drawn, and must be chosen appropriately. It should be capable of withstanding the currents at the specified voltage for the desired performance.

TVS-Diodes are typically used in various applications including protection against overvoltage, voltage spikes, ESD pulses, surges, and transients. The 5KP64-B in particular is used in a wide range of applications designed to protect against high voltage transients.
