LONG CREEPAGE TYPE HIGH ISOLATION VOLTAGE 4-PIN PHOTOCOUPLER −NEPOC
TM
Series−
DESCRIPTION
The PS2581L1, PS2581L2 are optically coupled isolators containing a GaAs light emitting diode and an
NPN silicon photo
transistor in a plastic DIP (Dual In-line Package).
Creepage distance and clearance of leads are over 8 millimeters.
The PS2581L2 is lead bending type (Gull-wing) for surface mounting.
