TVS - Diodes

TVS - Diodes commonly referred to as Transient Voltage Suppressors are semiconductor circuit protection devices providing an efficient, low-cost and reliable protection of sensitive components from damaging caused by transient over-voltage. The family of TVS diodes aim to protect delicate electronic devices from electric transient surges due to Electrostatic Discharge (ESD), lightning or other noise sources. TVS diodes are available in a variety of voltage, power, capacitance and time characteristics.

Some of the common applications for TVS include: DC/DC Converters, AC & DC lines, Telecom, Data & Signal, Power and automotive applications.

One of the more common TVS diodes available for industrial use is the TV04A280J-G. This TVS is designed to protect against voltage transients caused by lightning, electrostatic discharge (ESD) or other similar events.

The TV04A280J-G is a unidirectional device and it has two pins, anode and cathode, both of which are separated by a PEN (Polyethlyene Naphthalate) dielectric material. The anode is connected to the higher voltage terminal while the cathode is connected to the lower voltage terminal.

The TV04A280J-G has an operating voltage range of 6.5V to 8.2V and can effectively reduce a wide range of transient overvoltages. It also features low capacitance of 0.2pF and low stand-off voltage of 6.5V. This TVS is capable of dissipating up to 500W of power and preforms best when the current flow is slightly increased up to 0.3A.

When an overvoltage transient event occurs the device starts to conduct, limiting the voltage across the protected circuit. When the transient ends, the device is turned off and the protected circuitry resumes to its normal operation. During operation, the TV04A280J-G is able to clamp the voltage at a very low level and it also limits the duration of the transients.

In summary, the TV04A280J-G is an effective and reliable solution for providing ESD and lightning protection of sensitive electronics. It is suitable for a wide range of applications including DC/DC converters, AC & DC lines, telecom, data & signal, power and automotive applications.
