PHOTOCOUPLER
PS2861-1
HIGH ISOLATION VOLTAGE
4-PIN SOP PHOTOCOUPLER
−NEPOC
Series−
DESCRIPTION
The PS2861-1 is an optically coupled isolator containing a GaAs light emitting diode and an NPN silicon
phototransistor.
The PS2861-1 meets insulation thickness 0.4 mm and BSI′s insulation supplementary approved.
The package has shield effect to cut off ambient light, and is mounted in a plastic SOP (Small Outline Package) for
high density applications.
FEATURES
• Isolation distance (0.4 mm MIN.)
• High isolation voltage (BV = 2 500 Vr.m.s.)
• SOP (Small Outline Package) type
• High-speed switching (t
