TVS - Diodes

P6KE7.5HE3/73 Application Field and Working Principle

Transient voltage suppressors (TVS) are diodes that are specifically designed to protect circuits and components from transient voltages. The P6KE7.5HE3/73 can be considered a Unidirectional TVS. It\'s commonly used in I/O protection, low voltage cars, LED displays, automotive 12V/24V systems, set-top boxes, home appliances, and signal CPU of copiers and printers.TVS diodes can protect circuits against voltage spikes that are caused by static electricity, inductive/capacitive switching, lightning, and other events. They offer protection from different types of surges such as electrostatic discharge (ESD), electrical fast transients (EFT), and lightning surges.The P6KE7.5HE3/73 acts like a regular diode when a transient voltage exceeds its breakdown voltage (7.5V for this device). As the transient voltage increases, the diode becomes more conductive. This conductivity allows the voltage to be diverted to ground, thereby preventing it from reaching the protected circuitry.The P6KE7.5HE3/73 has several features that make it ideal for use in TVS applications. Its high surge capability allows it to absorb large transient current pulses (up to 1000A). It also has an extremely fast response time, which helps to protect sensitive electronics from even the shortest transients. In addition, its low dynamic resistance means that it can handle a large amount of power without becoming damaged or dissipating that power in the form of heat.The P6KE7.5HE3/73\'s non-linear current-voltage characteristics provide efficient protection. When the voltage exceeds the breakdown voltage of the device, the current of the circuit destines to increase abruptly. This causes a voltage drop across the TVS, reducing its effective breakdown voltage. This reverse avalanche effect calls a "clamping action" that suppresses the voltage and helps protect sensitive devices from dangerous voltage levels.Overall, the P6KE7.5HE3/73 offers a wide range of features and benefits for protecting against dangerous voltage transients. Its fast response time, high surge capability, and low dynamic resistance make it an ideal choice for applications like automotive 12V/24V systems, set-top boxes, home appliances, and signal CPU of copiers and printers.
