FEATURES
DESCRIPTION
• ISOLATION DISTANCE:
0.4 mm MIN.
NEC's PS2861-1 is an optically coupled isolator containing a
GaAs light emitting diode and an NPN silicon phototransistor.
This device's insulation thickness of 0.4 mm meets BSI's
supplementary insulation requirements. This package is
mounted in a plastic SOP (Small Out-line Package) for high
density applications and has a shield effect to cut off ambient
light.
• HIGH ISOLATION VOLTAGE:
BV = 2500 Vr.m.s.
• SOP (SMALL OUT-LINE PACKAGE)
• HIGH SPEED SWITCHING:
tr = 4 µs TYP, tf = 5 µs TYP
APPLICATIONS
• AVAILABLE ON TAPE AND REEL
• MODEM
• PROGRAMMABLE LOGIC CONTROLLERS
• POWER SUPPLY

1. Recommended Soldering Conditions
(1) Infrared reflow soldering
• Peak reflow temperature
235 ûC (package surface temperature)
• Time of temperature higher than 210 ûC
30 seconds or less
• 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).

Time (s)
(2) Dip soldering
• Temperature
260 ûC or below (molten solder temperature)
• Time
10 seconds or less
• 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) 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 side may enter the on state, even if the voltage is within the absolute maximum ratings.
