general description the pva30 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 rectifers 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 pva30 series combines very low solid-state output capacitance, very high off-state resistance and very fast response times. these photovoltaic relays are designed specifcally to accurately switch low-level signals in high- performance instrumentation systems. the pva30 series overcomes the limitations of both conventional electromechanical and reed relays by offering the solid state advantages of long life, fast operating speed, low pick up power, bounce-free operation, low thermal offset voltages and miniature package. these advantages allow product improvement and design innovations in many applications such as process control, multiplexing, automatic test equipment and data acquisition. the pva30 can switch analog signals from thermocouple level to 300 volts peak ac or dc polarity. signal frequencies into the rf range are easily controlled and switching rates up to 1.7khz are achievable. the extremely small thermally generated offset voltages allow increased measurement accuracies. these relays are packaged in 8-pin, molded dip packages and available with either thru-hole or surface-mount (gull- wing) leads, in plastic shipping tubes. applications ? process control ? data acquisition ? test equipment ? multiplexing and scanning features ? bounce-free operation ? 10 11 off-state resistance ? 1,000 v/sec dv/dt ? 0.2 v thermal offset ? 5 ma input sensitivity ? 4,000 v rms i/o isolation ? solid-state reliability ? ul recognized ? esd tolerance: 4000v human body model 500v machine model data sheet no. pd10050 revi series pva30npbf microelectronic power ic hexfet ? power mosfet photovoltaic relay single-pole, normally-open 0-300v ac/dc, 50ma part identifcation pva3054npbf pva3055npbf thru-hole pva3054nspbf pva3054ns-tpbf surface-mount tape and reel PVA3055NSPBF surface-mount (gull-wing) (hexfet is the registered trademark for international rectifer power mosfet s) www.irf.com 1
