general description the PVDZ172n photovoltaic relay is a single-pole, normally open solid state relay that can replace elec- tromechanical relays used for general purpose switch- ing of dc loads. it utilizes international rectifier?s hex- fet power mosfet as the output switch, driven by an integrated circuit photovoltaic generator of novel con- struction. the output switch is controlled by radiation from a gaalas light emitting diode (led) which is opti- cally isolated from the photovoltaic generator. these units overcome the limitations of both electro- mechanical and reed relays by offering the solid-state advantages of high sensitivity, miniaturization, no con- tact bounce, long operational life, insensitivity to exter- nal magnetic fields, shock and vibration, and high reli- ability inherent with solid state technology. they are ideally suited for switching high currents or low level signals without distortion or injection of electrical noise. these relays are packaged in 8-pin, molded dip pack- ages and available with thru-hole and surface-mount (gull-wing) leads, in plastic shipping tubes. data sheet no. pd 10039_d PVDZ172n microelectronic power ic hexfet ? power mosfet photovoltaic relay single pole, normally open 0-60v dc, 1.5a (hexfet is the registered trademark for international rectifier power mosfets) applications ! portable electronics ! programmable logic controllers ! computers and peripheral devices ! audio equipment ! power supplies and power distribution ! instrumentation part identification PVDZ172n thru-hole PVDZ172ns surface-mount (gull-wing) features ! 250m ? on-resistance ! bounce-free operation ! 1.5 amp capacity ! 4,000 v rms i/o isolation ! solid-state reliability ! ul recognized ! esd tolerance: 4000v human body model 500v machine model www.irf.com 1
