TVS - Diodes

TVS diodes are a type of overvoltage protection diode designed to secure circuits from voltage spikes. It is a semiconductor device that can be placed in parallel between two nodes. TVS diodes work by providing a low forward voltage drop which starts to conduct when the applied voltage reaches its clamping voltage. The TVS diode can dissipate large surge current in the event of an overvoltage, which is faster than traditional protection methods such as fuses.

5KP188AHE3/73 Application Field and Working Principle

5KP188AHE3/73 is an unidirectional TVS diode that limits transient overvoltages and is designed for use by electronics equipment manufacturers for protection of data and signal line applications. The 5KP188AHE3/73 TVS diode is designed with a breakdown voltage of 188 V, offering a low clamping voltage of 238 V, sustaining a surge capability of 5,000 watts. The package is a half-bridge type with built-in symmetry and designed with false soldering clips “F”.

The working principle of the 5KP188AHE3/73 is fairly simple, as it is designed to protect sensitive electronic components from high-voltage transients. When a voltage spike occurs, the 5KP188AHE3/73 quickly conducts current through the protection diode, diverting the transient current away from the protected components. This protects the protected components from damage due to the voltage spike, while providing a low forward voltage drop when the applied voltage is below the breakdown voltage.

The range of applications for the 5KP188AHE3/73 TVS diode is quite broad, as it can be used in various signal line and data protection applications. It is particularly well-suited for protection of power semiconductor devices, small appliances, consumer electronics, general purpose computers, and communication systems.

In summary, the 5KP188AHE3/73 is an unidirectional TVS diode with a breakdown voltage of 188 V and clamping voltage of 238 V. It can dissipate up to a surge capability of 5,000 watts, providing a reliable solution for protection of data and signal line applications from high-voltage transients. It is a cost-effective solution that is suitable for many applications, including protection of power semiconductor devices, small appliances, consumer electronics, general purpose computers, and communication systems.
