Series PVA33NPbF Microelectronic Power IC HEXFET® Power MOSFET Photovoltaic Relay Single-Pole, Normally-Open, 0-300V AC/DC, 150mA General Description The PVA33 Series AC Relay (PVA) is a single-pole, normally open, solid-state replacement for electromechanical relays used for general purpose switching of analog signals.
It utilizes International Rectifier’s HEXFET power MOSFETs as the output switches, driven by an integrated circuit photovoltaic generator of novel construction.
The output switch is controlled by radiation from a GaAlAs light emitting diode (LED), which is optically isolated from the photovoltaic generator.
The PVA33 Series overcomes the limitations of both conventional elec...
