FEPF16HTHE3/45

Diodes - Rectifiers - Arrays

The FEPF16HTHE3/45 is an integrated diode array chip designed to protect signals and data lines that interface with a microcontroller, or other digital device, from up to 7 different types of transient voltage enforcement. The device acts like a series of individual diodes by converting energy from the transient voltage into power, then shorting the voltage to ground. This prevents overvoltage that could cause damage to the device.

This device can be used in a variety of applications, including laptop, peripheral and telephone circuit protection, as well as device protection in computer, automotive and industrial applications. Its design offers superior air and arc immunity when compared to other diode arrays.

Application Field

The FEPF16HTHE3/45 is an integrated diode array chip designed for applications that require a high level of protection from electrical noise, such as laptop and peripheral circuit protection, telephone line protection, and device protection in automotive and industrial applications. It is also suitable for use in equipment powered by a DC source, such as computers, microwave ovens and medical equipment.

In addition, the device can be used as a voltage regulator or overvoltage protection circuit in a variety of applications, such as automotive electronics, communications systems, instrumentation, and control systems. It can also be used in power distribution, LED lighting, and consumer electronics.

Working Principle

The FEPF16HTHE3/45 is a diode array that is designed to protect signals and data lines from overvoltage events. It acts as a series of individual diodes and is composed of two major parts: a diode array and a bias resistor network. The diode array is composed of 16 power rectifiers in a 4x4 parallel configuration. Each rectifier is composed of 16 reverse biased PN junctioned diodes.

When a transient voltage is detected, the device converts the energy from the transient voltage into power, then shorts it to ground. This shorts out any other path to the affected line, preventing overvoltage that could cause damage to the device. The bias resistor network acts as a voltage regulator, providing a constant voltage across its terminals once the transient event is over.

In addition to providing superior protection against transient events, the device is also able to act as a transient voltage suppressor, clamping transient voltages that exceed the rated breakdown voltage. This helps to limit energy losses and damage to components.

The device is also capable of operating at high efficiencies, with power dissipation and efficiency values of up to 98%. This makes it well suited for applications where power efficiency is of paramount importance, such as LED lighting or consumer electronics.

Overall, the FEPF16HTHE3/45 is a reliable and efficient device designed to protect signals and data lines from overvoltage events. With superior performance and efficiency ratings, as well as its wide range of applications, this device is a valuable choice for industrial and consumer applications.
