Silicon Avalanche Photodiodes suit extreme low light conditions.
Press Release Summary:
Suited for applications with 400–1,100 nm wavelength, Silicon Avalanche photodiodes (Si APDs) are optical detectors that come in hermetic TO Cans and feature internal gain mechanism, rise times as low as 300 psec, and high sensitivity in NIR region. Optical sensitivity peak is optimized for 800 or 905 nm, and standard versions are available with 200, 500, and 800 µm active diameter. Additional characteristics include 80–200 V breakdown voltage and frequency response up to 1 GHz.

Marktech Introduces New Line of Silicon Avalanche Photodiodes
Cost-effective and ideally suited for extreme low light conditions, Marktech Silicon Avalanche photodiodes (Si APD) are the preferred optical detectors
Marktech Optoelectronics is pleased to introduce a new line of Silicon Avalanche Photodiodes. Marktech APD’s have an internal gain mechanism, fast time response, low dark current and high sensitivity in the near infrared region. These APD’s are recommended for applications that require high bandwidth, or where internal gain is needed to overcome high pre-amp noise. In addition, Marktech APD's provide higher sensitivity than a standard photodiode and are ideal for extreme low-level light detection and short pulse detection.
Silicon Avalanche photodiodes (Si APD’s) are the preferred optical detectors for applications where the wavelength lies between 400nm and 1100nm. Standard versions are available in three active area sizes:Â 200, 500 & 800um and are offered in hermetic TO Cans, and soon to be announced cost effective LCC packages.
According to Vince Forte, Marktech’s CTO, “Avalanche Photodiodes are used in a diverse range of applications. These detectors have become the semiconductor equivalent of photomultipliers in many applications including data communication, LIDAR, instrumentation and photon counting. Marktech is pleased to announce its first product offering of these new APDs and is able to customize devices to fit specific design requirements.”
Cost effective customization of these APDs is offered to meet exacting design specifications. Operation voltage selection and (Vbr) binning, wavelength specific band-pass filtering and hybridization options are among many of the application-specific solutions available at Marktech.
Marktech welcomes custom APD design challenges where the goal is to provide lead times to assist customers in getting product to market quickly.
