Hamamatsu Photonics S5973 is a precision infrared and visible light photodiode engineered for demanding optical detection applications. Housed in a rugged TO-18 metal package, this photodiode is ideal for industrial, laboratory, and commercial systems requiring accurate optical signal measurement.
The S5973 utilizes silicon PIN technology to provide broad-spectrum detection from 320nm to 1000nm, covering visible and near-infrared wavelengths. Peak sensitivity is achieved at 760nm, making this device suitable for fiber optic communication, high-speed photometry, and sensor interfaces. Its 65° angle of half sensitivity ensures effective light collection across varied incidence angles.
With a typical rise and fall time of just 0.6 nanoseconds, S5973 delivers fast response times pivotal for real-time optical monitoring and signal processing. The through-hole design and three-pin configuration facilitate simple PCB mounting in both experimental and production environments.
The device offers high reliability and is RoHS compliant. It operates in a temperature range from -25°C to 85°C, and its compact profile (height 3.6mm, length 8.2mm, width 6mm, diameter 5.4mm) allows easy fit within densely packed assemblies.
Key operating specifications include a short circuit current of 0.09μA, dark current of 0.5nA, and breakdown voltage of 25V. The photodiode features positive polarity and is supplied in tape & reel packaging for mass assembly.
Applications include optical fiber communication, scientific measurement, automated test systems, and sensing solutions in industrial automation, manufacturing, and laboratory electronics.
