DESCRIPTION
The PS2506-1, -2, -4 and PS2506L-1, -2, -4 are optically coupled isolators containing a GaAs light emitting diode
and an NPN silicon darlington connected phototransistor.
The PS2506-1, -2, -4 are in a plastic DIP (Dual In-line Package) and the PS2506L-1, -2, -4 are lead bending type
(Gull-wing) for surface mount.
FEATURES
• AC input response
• High isolation voltage (BV = 5 000 Vr.m.s.)
• High current transfer ratio (CTR = 2 000 % TYP.)
• High-speed switching (t
r
, t
f
= 100

s TYP.)
• Taping product number (PS2506L-1-E3, E4, F3, F4)
(PS2506L-2-E3, E4)
• UL approved (File No. E72422 (S) )
APPLICATIONS
• Power supply
• Telephone/FAX.
• FA/OA equipment
• Programmable logic controller
