TVS - Diodes
TVS (Transient Voltage Suppression) diodes are a type of semiconductor device used to protect electronic circuits from high energy transients, such as induced lightning or electrostatic discharge (ESD). They are characterized by fast acting, non-destructive protection and come in a variety of shapes and sizes. TVS diodes are designed to clamp and absorb high voltage transients, and dissipate the energy dissipated through them as heat. They can also provide EMI and RFI (electromagnetic interference and radio frequency interference) protection.

1.5KE75CAHE3_A/C is a unidirectional transient voltage suppressor, which is used to protect device and electronic components from electrostatic discharge, electric over voltage, surge, and other transient oscillations in electrical systems. It is comprised of an epoxy resin package with a PN junction and a pair of terminals for connecting to other elements, such as a metal oxide varistor (MOV). The device operates in a low forward voltage drop mode and is designed to have a fast response time to prevent over-voltage damage.

The working principle of 1.5KE75CAHE3_A/C is simple. High voltages or ESD pulses are absorbed by the PN junction and are converted into little heat. The resulting current is then clamped so that the levels are within specified limits. This device are most suitable for protecting sensitive electronic equipment from over-voltage or short-duration high voltage transients from lightning or from other sources.

1.5KE75CAHE3_A/C function as a clamp and absorb the high voltages and surges instead of diverting them away from the protected circuits. These components are also capable of efficiently redirecting fast-rising over-voltage impulses. This feature is useful in rapidly increasing the voltage drop across the PN junction when the current flow exceeds the device’s surge current ratings.

1.5KE75CAHE3_A/C devices are also used in a variety of applications like controlling over-voltage conditions in communication equipment, computers, high-speed data and audio circuitry, and digital switching systems. They are used in power-limited circuits, where they provide secondary surge absorption and protection. Since these components can not only reduce electric shock hazards, but also prevent excessive current surges, they are often used in power converters, power conditioners, and inverters.

To sum up, 1.5KE75CAHE3_A/C is a type of TVS diode that is designed to protect electronic circuits and components from transient voltages and surges. It has a low forward voltage drop and absorbs high voltages and surges by means of a PN junction. In addition, it efficiently redirects fast-rising over-voltage impulses and is used in a variety of applications, such as controlling over-voltage conditions in communication equipment, computers, high-speed data and audio circuitry, and digital switching systems.
