Description

The RVSX series is a TVS family created to provide simple and effective solutions for designers working on circuits that require protection from repetitive overvoltages. The RVSX series is highly reliable and suits applications where the surge frequency makes the protected device temperature increase, for example, MOSFET protection in fly back configuration. Additional support for designers using these devices is available in the STMicroelectronics application note AN4209: “Design methodology for repetitive voltage suppressors (RVS) in repetitive mode: RVS”.
