The International Rectifier Solid State Relays – PCB Mount 400V 2 Form A Photo Voltaic Relay (PVT422PBF) is a high performance, reliable, and compact opto-relay from Infineon's PVT family. This low-resistance, passivated-silicon tetrode device offers superior EMC performance and is fast-switching for very low power loss in photo voltaic applications. Its 400V nominal drain-source voltage and 3A maximum peak load current make it a good choice for medium to high-powered circuits. The unit is also capable of working in hostile environments, making it suitable for outdoor applications. It has a rated lifetime of at least 100,000 cycles, and is lightweight and compact, making it easy to deploy and install. The relay features multiple protection features, such as current limitation, thermal protection, and transient protection, for even better performance and safety.
