PHOTOCOUPLER
PS2802-1,PS2802-4
HIGH ISOLATION VOLTAGE
DARLINGTON TRANSISTOR TYPE
SOP PHOTOCOUPLER
−NEPOC Series−
DESCRIPTION
The PS2802-1 and PS2802-4 are optically coupled isolators containing a GaAs light emitting diode and an NPN
silicon darlington-connected photo transistor in a plastic SOP for high density applications.
This package has shield effect to cut off ambient light.
FEATURES
• High isolation voltage (BV = 2 500 Vr.m.s.)
• Small and thin package (4,16-pin SOP, Pin pitch 1.27 mm)
• High current transfer ratio (CTR = 2 000 % TYP. @ IF = 1 mA, VCE = 2 V)
• Ordering number of tape product: PS2802-1-F3, F4, PS2802-4-F3, F4
• Safety standards: PS2802-1, -4
• UL approved: File No. E72422 (S)
• BSI approved: No. 8188, 8189
• VDE0884 approved (Option): PS2802-4 only
APPLICATIONS
• Programmable logic controllers
• Measuring instruments
• Hybrid IC

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

(2) Wave soldering
• Temperature
• Time
• Preheating conditions
• Number of times
• Flux
260°C or below (molten solder temperature)
10 seconds or less
120°C or below (package surface temperature)
One (Allowed to be dipped in solder including plastic mold portion.)
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.
