HI
GH ISOLATION VOLTAGE AC INPUT, DARLINGTON TRANSISTOR TYPE
DESCRIPTION
The PS2506-1 and PS2506L-1 are optically coupled isolator containing two GaAs light emitting diodes and
an NPN silicon Darlington-connected phototransistor. The PS2506-1 is a plastic DIP (Dual In-li ne Pack ag e)
model for the pin Insertion mounting and the PS2506L-1 is a Gull-wing lead bending model modified from the
PS2506-1 for the surface mounting.
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

, t
f
= 100 µs TYP.)
• Embossed tape product: PS2506L-1-F3 : 2 000 pcs/r eel
• Pb-free product
• Safety standards
• UL approved: UL1577, Double protection
APPLICATIONS
• Power supply
• Telephone/FAX
• FA/OA equipment
• Programmable logic controller
