Thyristors – SCRs - Modules

The EFF16F is a Thyristor Module for very high power rectification applications. It is a third-generation thyristor, introduced by EPCOS Bourns in the 90’s for use in power electronics. The device is based on a Silicon carbide substrate, utilizing modern multi-finger FET design and fabrication methods. The device offers significantly increased reliability and efficiency of power rectification systems and can be combined with other SCR devices in the same package.

The EFF16F is a part of the EPCOS Bourns family of high power switching semiconductor devices. It is designed to be an efficient, low cost solution for many high current applications. The module is capable of carrying currents of up to 1000A, with very low switching losses and high positive temperature coefficient. With its robust construction and design for higher temperature applications, it is ideal for harsh operating environments such as automotive, industrial and off-shore installations.

The primary application of the EFF16F is as a main switching device in high power rectification systems. It is used in power converters and inverters, ideally in applications where the forward voltage drop must be minimized while still providing an efficient and cost effective solution. It is also used in boost and buck converters, DC-DC converters, and in DC-AC inverters.

The working principle of the EFF16F is based on a variety of different technologies. The device is a controlled rectifier, meaning it will allow current to flow in one direction only, when a certain voltage threshold has been reached. It is also capable of being accelerated, meaning the speed at which the current can flow can be increased by increasing the gate voltage. The range of control signals is from 0V to the full breakdown voltage of the device. The device is also capable of being triggered in either positive or negative polarity.

The EFF16F utilizes a bi-directional low voltage gate drive signal and a source-gate isolated power driver amplifier, to drive the switch. This enables the use of optically isolated low voltage control signals up to 16F over a wide range of signal amplitudes. The device also features an integrated bypass diode for reverse current protection, a built-in overtemperature shutdown feature, and an integrated active damping circuit.

The EFF16F is a versatile and powerful Thyristor Module solution for many power rectification applications. It combines the benefits of high-power SCR technology with a low overall cost, making it an attractive choice for a wide range of demanding applications. The module offers a power efficient solution and provides a reliable, high-performance, and cost-effective solution to many critical power rectification applications.
