Avalanche Photo Detectors

Marktech Si APD’s offer low-level light and short pulse detections of wavelengths between 400 nm and 1100 nm. They feature a choice of either a 230 μm or 500 μm active area; optical sensitivity optimizations for 800 nm or 905 nm peak response; an internal gain mechanism; high gain at low bias voltage; extremely fast rise times as low as 300 ps; frequency response to 1 GHz; and a low breakdown voltage of 80V-200V. Units are also RoHS compliant. Standard Si APDs are offered with multiple customization options, including operational voltage selection, wavelength specific band-pass filtering, and hybridization. Package options include hermetically sealed TO metal cans and cost-effective SMD (LCC) types, with additional customization by request.

Silicon APDs from Marktech Optoelectronics offer low-level light and short pulse detections of wavelengths between 400 nm and 1100 nm. As precision measurement devices, Marktech Silicon APDs offer low dark current and significantly higher sensitivities, including higher near-infrared (NIR) spectral sensitivity, than can be achieved with a standard photodiode. This allows the Silicon APDs to serve as the semiconductor near-equivalent to photomultipliers within a myriad of applications. It also allows them to accurately detect weaker light intensities, in applications where higher bandwidth or internal gain may be required, in order to overcome higher preamplifier noise levels.

Standard and custom Silicon APDs are available in quantities from prototype to OEM volumes. Via its global distribution partner, DigiKey Corporation, Marktech offers the industry’s largest selection of standard off-the-shelf Silicon APDs for immediate customer delivery. For an up-to-date listing of available standard product inventory, please see below. For customers who require a more unique solution, custom Silicon APDs, in virtually any-sized quantities, are available in as few as 6-8 weeks from prototype approvals, on average. Please consult the factory for applications engineering assistance.

Notes

In the interest of continuous quality improvement, product specifications for Marktech Silicon APDs are subject to change without notice. Marktech Silicon APDs are ESD sensitive products. End users are therefore recommended to follow appropriate ESD control handling precautions, and to keep static-sensitive devices in their static-protective bags until installation.
