Handling Precautions
signal is unstable. Please do not use the unstable signal as the output signal.
Moisture-Proof Packing
Insert a bypass condenser of up to 0.1μF between V
When Vcc is turned on it takes at least 200 ms for the internal circuit to stabilize. During this time the output
Select a road resistor (R
Calculation example of minimum road resistor: R
Mounting Precautions
To avoid moisture absorption by the resin, the product is packed in an aluminum envelope with silica gel.
Since the optical characteristics of the device can be affected during soldering by vaporization resulting
from prior absorption of moisture and they should therefore be stored under the following conditions:
TPS859 uses a clear resin, and delicate handling is necessary for it.
The characteristic change or the product might be damaged by the handling method of mounting.
Please note the following and handle the product.

1. If the aluminum bag has been stored unopened
2. If the aluminum bag has been opened
3. Baking should be conducted within 72 h after the humidity indicator shows > 30% or the bag seal date
4. When the photointerrupter is baked, protect it from electrostatic discharge.
5. Do not toss or drop to avoid damaging the moisture-proof bag.
Vsat:(Supply voltage(Vcc))-(Maximum value of saturation output voltage)=0.4V
is over 6 months. The number of baking should be once. If the baking is conducted repeatedly, it may
affect the peel-back force and cause a problem for mounting.

Time: 6 months
Temperature: 5 to 30°C
Relative humidity: 70% RH (max)
Time: 168 h
Baking condition: 60 ± 5°C, 12 to 24 h
Storage period: 6 months from the seal date on the label
Do not apply stress to the resin at high temperature. Time until the product returns at the normal
temperature after mounting of the reflow is different according to the mounting substrate and the
environment. Please do not give the stress with heat remained in the product.
The resin part is easily scratched, so avoid friction with hard materials.
When installing the assembly board in equipment, ensure that this product does not come into
contact with other components.
Please confirm the heat contraction of the substrate of the reflow mounting doesn't influence the
product. The load is given to the product by mounting that the heat contraction is large on the
substrate and the installation position of the substrate. Please note that the characteristic changes or
the product might be damaged.
