PS2502-1,-2,-4,PS2502L-1,-2,-4
HIGH ISOLATION VOLTAGE
DARLINGTON TRANSISTOR TYPE
MULTI PHOTOCOUPLER SERIES
−NEPOC Series−
DESCRIPTION
The PS2502-1, -2, -4 and PS2502L-1, -2, -4 are optically coupled isolators containing a GaAs light emitting diode
and an NPN silicon darlington connected phototransistor.
The PS2502-1, -2, -4 are in a plastic DIP (Dual In-line Package) and the PS2502L-1, -2, -4 are lead bending type
(Gull-wing) for surface mount.
