5mm T-1 3/4
Ambient Light Sensor
ALS-PDT243-3C/L451
Features
‧Light to Current, analog output
‧Good output linearity across wide illumination range
‧Operation temperature performance, -30oC to 85oC
‧Wide supply voltage range, 3V to 24V
‧High efficiency light current output
‧Lower dark current 0.1uA
‧Lower cost
‧Size : 5mm Lamp (Flat lens)
‧RoHS compliant and Pb Free package
Description
The ALS-PDT243-3C/L451 is an ambient light sensor using a photo transistor in
a DIP package. It is used to replace traditional CdS sensors, since Cadmium is
no longer allowed by RoHS.
Applications
‧Detection of ambient light to control electrical unit
Lighting devices – Road lamp, Night lamp
Consumer device – LCD TV, Toys, Gaming
