The PLA134 is a 1-Form-A solid state relay which uses optically coupled MosFET technology to provide 3750V of input to output isolation. The efficient MosFET switches and photovoltaic die use Clare's patented OptoMOS architecture. The optically-coupled input is controlled by a highly efficient GaAIAs infrared LED. The PLA134's combination of low on resistance and high load current handling makes it suitable for a variety of industrial applications. Because solid state relays have no moving parts, they can offer faster, bounce-free switching in a more compact surface mount or through hole package than traditional electromechanical relays.
