Silicon Photodiode Has Large Active Area

Claimed as the largest active area photodiode available in a 5-mm plastic package, the CLD370F measures 2 mm x 2 mm and provides the highest output or the highest sensitivity available in the package size. Typical light current at Ee = 1.0 mW/cm² is 60 µA. And the plastic package’s dark tint attenuates wavelenghts shorter than 700 nm. In most applications, this eliminates the need for signal modulation or filtering to reduce visible light problems. To help ensure the accuracy of the chip, physical support has been improved by widening the top of the lead frame. Typical applications include the absence/presence sensing required in instrumentation and industrial control.
