TVS - Diodes

TVS - Diodes, also known as transient voltage suppressors, are components that serve the primary purpose of limiting peak voltage to a safe lower level when a voltage spike or surge occurs. They work by placing a diode across the voltage source or a line. This diode will then be placed in a forward bias state when the voltage exceeds the peak positive breakdown voltage level some of these devices can handle, thus allowing current to pass through the diode.

The MP4KE47AE3 is a high-speed light signal diode manufactured by Philips. It is a dual TVS diode designed to protect equipment from the destructive effects of electrostatic discharge (ESD). The junction capacitance of the diode is designed to limit the rise time of ESD surge pulses and minimize damage. The device is available in various packages and has an operating range from -55°C to 150°C.

This diode will reduce a range of peak surge voltages from 400V to 600V in the reverse direction by clamping it to the breakdown voltage. It is typically used in automotive applications such as seatbelt pretensioners and keyless entry systems which require protection from heavy load switching. They are also suitable for use in data communication lines, printers, telecommunication systems, and automotive security systems.

The MP4KE47AE3 is equipped with integrated overvoltage protection to provide a second level of protection against sudden peak voltages. It operates with an avalanche breakdown voltage of 40V to 50V, depending on the type of transient peak voltage protection. It can withstand up to 50A of pulses up to 5/10µs and can be used in peak power levels of up to 0.5A. Its high efficiency makes it ideal for many low-voltage, low-power applications.

The MP4KE47AE3 is designed for simple protection of single-ended and differential line-side applications. It connects to the source voltage using a dedicated line or series diode and an additional clamp element that traps excessive voltages on the line. The diode is designed to limit the maximum input voltage to no more than the breakdown voltage, which in turn will protect the connected equipment from overload.

The MP4KE47AE3 is a cost-effective device that provides a high level of protection against surges. It is available in various packages and has an ESD rating of up to ±1000V on contact. The device can be used in a wide variety of applications, including automotive, telecommunications, consumer electronics, medical, and industrial.
