The Infineon T720N16TOFXPSA1 is a Hockey-puck thyristor designed for use in power switching applications. It has a voltage rating of 1.6kV, current rating of 720A and a firing circuit current of 250mA. Its peak off-state blocking voltage is also 1.6kV and its normal on-state current is rated at 720A with an ifsm rating of 12.5kA. This makes it an ideal choice for applications that require heavy current loads, such as motor control, UPS systems, and industrial control systems. Its rugged and reliable construction is suitable for use in harsh environments, and its high temperature operation allows for improved performance and long life.
