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

Data Sheet PN10399EJ02V0DS

PS2805A-1,PS2805A-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 side 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.
