Explore company information and manufacturing capabilities, then discuss the scope of your project with a relevant supplier.
Photodiodes offer faster response times but require external amplification, while phototransistors provide higher sensitivity and built-in gain but slower switching speeds. Selection depends on application speed and sensitivity requirements.
Temperature variations affect dark current (doubles every 10°C rise), responsivity (decreases with temperature), and CTR (typically decreases 0.5-1.0%/°C). Proper thermal design and derating are essential for reliable operation.
