PHOTOCOUPLER
PS2502-1,-4,PS2502L-1,-4
HIGH ISOLATION VOLTAGE
DARLINGTON TRANSISTOR TYPE
MULTI PHOTOCOUPLER SERIES
−NEPOC 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.
FEATURES
• High isolation voltage (BV = 5 000 Vr.m.s.)
• High current transfer ratio (CTR = 2 000% TYP.)
• High-speed switching (tr, tf = 100 µs TYP.)
<R> • 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
• Programmable logic controller

(4) Cautions
• Fluxes
Avoid removing the residual flux with freon-based and chlorine-based cleaning solvent.
2. Cautions regarding noise
Be aware that when voltage is applied suddenly between the photocoupler’s input and output or between
collector-emitters at startup, the output transistor may enter the on state, even if the voltage is within the absolute
maximum ratings.
3. Measurement conditions of current transfer ratios (CTR), which differ according to photocoupler
Check the setting values before use, since the forward current conditions at CTR measurement differ according
to product.
When using products other than at the specified forward current, the characteristics curves may differ from the
standard curves due to CTR value variations or the like. Therefore, check the characteristics under the actual
operating conditions and thoroughly take variations or the like into consideration before use.
USAGE CAUTIONS
1. Protect against static electricity when handling.
2. Avoid storage at a high temperature and high humidity.
