PHOTOCOUPLER
PS2502-1,-4,PS2502L-1,-4
HIGH ISOLATION VOLTAGE
NEPOC Series
DARLINGTON TRANSISTOR TYPE
MULTI PHOTOCOUPLER SERIES
DESCRIPTION
The PS2502-1, -4 and PS2502L-1, -4 are optically coupled isolators containing a GaAs light emitting diode and an
NPN silicon darlington connected phototransistor.
The PS2502-1, -4 are in a plastic DIP (Dual In-line Package) and the PS2502L-1, -4 are lead bending type (Gull-
wing) for surface mount.
