Infineon’s 50mm/60mm Modules Contain Both Thyristor and Diode Switches
Infineon's newest thyristor/diode modules include 50mm modules with solder bond technology and 60mm modules with pressure contact technology.
Infineon Technologies has announced its newest thyristor/diode modules, which includes the Prime Block 50mm modules with solder bond technology and the 60mm modules with pressure contact technology.
The newest Prime Block modules are geared toward industrial AC and DC drives and for rectifiers and bypasses in uninterrupted power supply (UPS) systems.

The modules are designed for high performance when the desired current exceeds 600A for a 60mm module or 330A for the 50mm module.
This feature can be an advantage for engineers, as it doesn’t require paralleling of modules, which is not always a viable option.
Key Features of 50mm Modules
The newest 50mm footprint has the highest current rating available for its size. It uses Infineon's solder bond technology, a process that is 100% x-ray monitored.
Infineon claims that this enables predictably high performance and lifetime. The 50mm modules also include a solid base plate for mounting.
50mm housing comes in either a thyristor/thyristor, thyristor/diode, or diode/diode topology with a blocking voltage of 1600V, 1800V, and 2200V and supports current ratings up to 390A.
Key Features of 60mm Modules
The 60mm modules are built to offer a power density that prevents any paralleling of modules and "best-in-class" DC blocking capability. It is also said to have a high surge current in 60mm housing.

The modules include pressure contact technology with a short-on-fail feature and high overload capability.
60mm housing comes in either a thyristor/thyristor or thyristor/diode topology with a blocking voltage of 1600V or 2200V and in current ratings from 700A to 820A.
Thyristor/Diode for Industrial Automation and UPS
Control systems for industrial automation require the use of sensors, microcontrollers, and power components for the high demands of various industries.
Rectifiers play a major role in motor control as they concert alternating current (AC) to direct current (DC) and allow the current to flow in only one direction.
Diodes differ from thyristors as they only have two terminals, an anode and a cathode. Thyristors, on the other hand, have three terminals, which also include a gate that provides external triggering.
Infineon intends for the Prime Block modules to allow for flexibility in configurations as they contain both thyristor and diode switches.

Rectifiers used in UPS systems convert AC to DC and charge the batteries of the system. The thyristor/diode modules can also be used as a bypass to ensure power is maintained in the event of a UPS failure.
Due to the critical nature of the systems, reliability is crucial for the modules. To help optimize UPS systems, the Prime Block offers high power density in its respective footprint.
