Description
The ALS-PT204-6C/L177 is consisting of a phototransistor in 3mm lamp. EVERLIGHT ALS series products are good effective solution to the power saving of display backlighting of mobile appliances, such as the mobile phones, NB and PDAs. Due to the high rejection ratio of infrared radiation, the spectral response of the ambient light sensor is close to human eyes.
Applications
?Detection of ambient light to control display backlighting
Mobile devices – mobile phones, PDAs
Computing device – TFT LCD monitor for Notebook computer
Consumer device – TFT LCD TV, video camera, digital camera, toys
?Automatic residential and commercial management
?Automatic contrast enhancement for electronic signboard
?Ambient light monitoring device for daylight and artificial light – Street light, CCD/CCTV

Recommended method of storage
Reflow Terms: JEDEC Level 4 Specification
Dry box storage is recommended as soon as the aluminum bag has been opened prevent 1. Over-current-proof
Customer must apply resistors for protection, otherwise slight voltage shift might cause big current happen. (Burned-out might happen).
2. Storage
(1) Do not open moisture proof bag before components are ready to use.
(2) Before opening moisture proof bag, components should be kept at 30℃ or less and
90%RH or less.
(3) Components should be used within a year.
(4) After opened moisture proof bag, components should be kept at 30℃ or less and
70%RH or less.
(5) Components should be used within 168 hours after opened moisture proof bag.
(6) If the moisture absorbent material (silica gel) has faded away or the components
have exceeded the storage time, baking treatment should be performed using the following conditions. (Baking treatment: 60±5℃ for 24 hours)
ESD Precaution:
Proper storage and handing procedures should be followed to prevent ESD damage to
the devices especially when they are removed from the Anti-static bag. Electro-Static Sensitive Devices warning labels are on the packing.

Recommended Solder Profile
Notice:
(1) Reflow soldering should not be done more than two times.
(2) When soldering, do not put stress on the devices during heating.
(3) After soldering, do not warp the circuit board.
Soldering Iron
Each terminal is to go to the tip of soldering iron temperature less than 350℃for 3 seconds within once in less than the soldering iron capacity 25W. Leave two seconds and more intervals, and do soldering of each terminal. Be careful because the damage of the product is often started at the time of the hand solder.
