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.
FEATURES
• High isolation voltage (BV = 5 000 Vr.m.s.)
• High current transfer ratio (CTR = 2 000% TYP.)
• High-speed switching (t
r, tf = 100
μ
s TYP.)
• Ordering number of tape product: PS2502L-1-F3: 2 000 pcs/reel
• Safety standards
• UL approved: No. E72422
APPLICATIONS
• Power supply
• Telephone/FAX
• FA/OA equipment
