In the realm of electronic components that play a critical role in converting light into electrical signals, the OP950 PIN Silicon Photodiode stands out with its unique features and broad applicability. Introduced in the June 1996 product bulletin by Optek Technology, Inc., this photodiode is designed to capture spectral responses across visible to infrared light wavelengths, thanks to its clear epoxy packaging. Its wide receiving angle ensures consistent reception over a broad area, while its side-looking package caters to space-constrained applications, making it an ideal choice for integration into various electronic assemblies. The OP950's compatibility with Optek’s series of infrared emitting diodes, along with its fast switching time, underlines its utility in creating efficient optical coupling, crucial for high-speed data transmission and sensing applications. A highlight in its design includes the ability to withstand substantial environmental and operational stresses, demonstrated by its absolute maximum ratings which encompass a reverse breakdown voltage of 60V and a significant tolerance to temperature variations and soldering heat. These attributes, along with the detailed electrical characteristics provided by Optek, such as reverse light and dark current specifications, and performance curves covering aspects from light current vs. irradiance to switching times, position the OP950 as a robust and versatile component in the field of optoelectronics.

Notes:
(1)RMA flux is recommended. Duration can be extended to 10 sec. max. when flow soldering. Max. 20 grams force may be applied to leads when soldering.
(2)Derate linearly 1.67 mW/o C above 25o C.
(3)Light source is an unfiltered GaAs LED with a peak emission wavelength of 935nm and a radiometric intensity level which varies less than 10% over the entire lens surface of the photodiode being tested.
(4)To calculate typical dark current in μA, use the formula ID = 10(0.042
