Photodiodes are semiconductors that generate a current or voltage when illuminated by light. They have no internal gain, but can operate at much higher light levels than other detectors. Hamamatsu Si photodiodes have low capacitance and dark current, which reduces noise and increases speed. (read more)

API has two fully equipped silicon-wafer fabricating facilities for processing silicon photodiodes. Our facilities in California (Class 10,000 rated) and Wisconsin (Class 1,000 rated) support custom detector development from initial prototypes to high-volume manufacturing. (read more)

Designed to protect your sensitive closed circuit TV system from surges, the CCTV uses only silicon avalanche suppression diodes (SASD), providing protection for your camera's RF signal via pass-through BNC connectors. It protects both 24 volt AC and DC and 2-wire RS 232 signals (for pan-tilt-zoom control) via pass-through terminal blocks.
