PHOTOCOUPLER
PS2561-1,-2, PS2561L-1,-2
HIGH ISOLATION VOLTAGE
SINGLE TRANSISTOR TYPE
MULTI PHOTOCOUPLER SERIES
The mark
shows major revised points.
DESCRIPTION
The PS2561-1, -2 and PS2561L-1, -2 are optically coupled isolators containing a GaAs light emitting diode and an
NPN silicon phototransistor.
PS2561-1, -2 are in a plastic DIP (Dual In-line Package) and PS2561L-1, -2 are lead bending type (Gull-wing) for
surface mount.
FEATURES
High isolation voltage
BV = 5 000 Vr.m.s.: standard products
BV = 3 750 Vr.m.s.: VDE0884 approved products (Option)
High collector to emitter voltage (V
