Description

NEC's PS2861-1 is an optically coupled isolator containing a GaAs light emitting diode and an NPN silicon phototransistor. This device's insulation thickness of 0.4 mm meets BSI's
supplementary insulation requirements. This package is mounted in a plastic SOP (Small Out-line Package) for high density applications and has a shield effect to cut off ambient light.
