PS2501-1,-4,PS2501L-1,-4
HIGH ISOLATION VOLTAGE
SINGLE TRANSISTOR TYPE
MULTI PHOTOCOUPLER SERIES
NEPOC Series
DESCRIPTION
The PS2501-1, -4 and PS2501L-1, -4 are optically coupled isolators containing a GaAs light emitting diode and an
NPN silicon phototransistor.
The PS2501-1, -4 are in a plastic DIP (Dual In-line Package) and the PS2501L-1, -4 are lead bending type (Gull-
wing) for surface mount.
