Category
This 450-1700nm photodiode with 20V reverse voltage tolerance and 120nA dark current is optimized for precision optical detection in communication and sensing systems. Its operating range up to +85°C enables industrial applications but requires careful thermal management. Soldering must maintain fine pitch integrity while storage conditions prevent ESD damage. Alternative models match critical parameters but differ in cost and availability. Best suited for high-reliability systems where wavelength specificity and voltage tolerance are primary requirements.
