DESCRIPTION
The PS2561D-1 is an optically coupled isolator containing a GaAs light emitting diode and an NPN silicon
phototransistor.
The PS2561D-1 is in a plastic DIP (Dual In-line Package) and the PS2561DL-1 is lead bending type (Gull-
wing) for surface mount.
The PS2561DL1-1 is lead bending type for long creepage distance.
The PS2561DL2-1 is lead bending type for long creepage distance (Gull-wing) for surface mount.
FEATURES
Operating ambient temperature: 110C
High isolation voltage (BV = 5 000 Vr.m.s.)
High collector to emitter voltage (V
CEO
= 80 V)
High current transfer ratio (CTR = 160% TYP.)
High-speed switching (t
