TVS - Diodes

The 5KP7.5A-E3/73 is a transient voltage suppressor diode, which is a widely used component in various electronic applications and provides protection against voltage spikes or transients. A TVS diode has a reverse voltage rating of 5KP7.5A-E3/73, and it is designed to protect electronic devices from transient voltages caused by events such as electrostatic discharges, lightning strikes, power surges, inductive loads, and more. The 5KP7.5A-E3/73 diode works by clamping the voltage across it when the voltage exceeds a certain level. It is a unique and valuable component in the protection of high-voltage and high-current applications.

Application Field

TVS diodes are widely used to protect electronic components from destructive voltage spikes or transients and are commonly employed in mains-power switching applications to protect against power surges, as well as in high-speed computer interfaces that experience multiple ESD events. TVS diodes are also used in automotive electronics, lighting systems, communications systems, and in many other applications that require transient voltage protection. In general, TVS diodes are used where circuit protection from high-voltage transients is paramount.

Working Principle

TVS diodes are manufactured to clamp transient over-voltages and protect circuits and components from damage due to excessive current or voltage. When a transient voltage spike occurs, the TVS diode will clamp the voltage to a level below the breakdown voltage of the components in the circuit. This protects the components in the circuit from dangerous voltages. The TVS diode works in a similar way to a standard diode since it has a ‘cut-in’ voltage and a ‘breakdown’ voltage. All the excess current will be diverted by the diode allowing the voltage to remain in a safe region, and the diode prevents voltages from exceeding the specified breakdown voltage.

TVS diodes are capable of suppressing and absorbing transient voltages and currents far greater than the current flow in the circuit. The power dissipation of a TVS diode is dependant on the circuit and the diode type used. TVS diodes are capable of withstanding voltages much higher than necessary to protect the components in the circuit. This means they provide the best possible protection while still allowing the current to flow in the circuit with minimal losses.
