PS2861-1

NEC's HIGH ISOLATION VOLTAGE 4-PIN SOP OPTOCOUPLER FEATURES ISOLATION DISTANCE: 0.4 mm MIN. HIGH ISOLATION VOLTAGE: BV = 2500 Vr.m.s. SOP (SMALL OUT-LINE PACKAGE) HIGH SPEED SWITCHING: tr = 4 µs TYP, tf = 5 µs TYP AVAILABLE ON TAPE AND REEL PS2861-1 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.
