PHOTOCOUPLER
PS2501-1,-2,-4, PS2501L-1,-2,-4
HIGH ISOLATION VOLTAGE
SINGLE TRANSISTOR TYPE
MULTI PHOTOCOUPLER SERIES
−NEPOC Series−
DESCRIPTION
The PS2501-1, -2, -4 and PS2501L-1, -2, -4 are optically coupled isolators containing a GaAs light emitting diode
and an NPN silicon phototransistor.
The PS2501-1, -2, -4 are in a plastic DIP (Dual In-line Package) and the PS2501L-1, -2, -4 are lead bending type
(Gull-wing) for surface mount.
FEATURES
• High isolation voltage (BV = 5 000 Vr.m.s.)
• High collector to emitter voltage (VCEO = 80 V)
• High-speed switching (tr = 3 µs TYP., tf = 5 µs TYP.)

NOTES ON HANDLING
1. Recommended soldering conditions
(1) Infrared reflow soldering
• Peak reflow temperature
260°C or below (package surface temperature)
• Time of peak reflow temperature
10 seconds or less
• Time of temperature higher than 220°C
60 seconds or less
• Time to preheat temperature from 120 to 180°C
120±30 s
• Number of reflows
Three
• Flux
Rosin flux containing small amount of chlorine (The flux with a
maximum chlorine content of 0.2 Wt% is recommended.)
Package Surface Temperature T (˚C)

Time (s)
(2) Wave soldering
• Temperature
260°C or below (molten solder temperature)
• Time
10 seconds or less
• Preheating conditions
120°C or below (package surface temperature)
• Number of times
One (Allowed to be dipped in solder including plastic mold portion.)
• Flux
Rosin flux containing small amount of chlorine (The flux with a maximum chlorine
content of 0.2 Wt% is recommended.)
(3) Soldering by soldering iron
• Peak temperature (lead part temperature)
350°C or below
• Time (each pins)
3 seconds or less
• Flux
Rosin flux containing small amount of chlorine (The flux with a
maximum chlorine content of 0.2 Wt% is recommended.)
(a) Soldering of leads should be made at the point 1.5 to 2.0 mm from the root of the lead.
(b) Please be sure that the temperature of the package would not be heated over 100°C.

PS2501-1,-2,-4, PS2501L-1,-2,-4
(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.
USAGE CAUTIONS
1. Protect against static electricity when handling.
2. Avoid storage at a high temperature and high humidity.
