data sheet no. pd10054 revg series pvi-npbf photovoltaic isolator single and dual channel 5-10 volt output general description the pvi series photovoltaic isolator generates an electrically isolated dc voltage upon receipt of a dc input signal. it is capable of directly driving gates of power mosfets or igbts. it utilizes a monolithic integrated circuit photovoltaic generator of novel construction as its output. the output is controlled by radiation from a gaalas light emitting diode (led), which is optically isolated from the photovoltaic generator. the pvi series is ideally suited for applications requiring high-current and/or high-voltage switching with optical isolation between the low-level driving circuitry and high-energy or high-voltage load circuits. it can be used for directly driving gates of power mosfets. the dual-channel device allows its outputs to drive independent discrete power mosfets, or be connected in parallel or in series to provide higher current drive for power mosfets or higher voltage drive for igbts. the pvi series photovoltaic isolators employ fast turn-off circuitry. these pvi series photovoltaic isolators 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 features ? isolated voltage source ? monolithic construction ? up to 8 a output ? single or dual output ? solid-state reliability part identifcation pvi1050npbf pvi5050npbf pvi5080npbf pvi1050nspbf pvi5050nspbf PVI5080NSPBF pvi1050ns-tpbf thru-hole surface-mount (gull-wing) surface-mount, tape and reel www.irf.com 1 ? load distribution ? industrial controls ? current-to-voltage conversion ? custom solid-state relay
