IF-D93: Plastic Fiber Optic Photodarlington

The IF-D93 is a very high-sensitivity photodarlington detector housed in a "connector-less" style plastic fiber optic package. Optical response of the IF-D93 extends from 400 to 1100 nm, making it compatible with a wide range of visible and near-infrared LEDs and other optical sources. This includes 650 nm visible red LEDs used for optimum transmission in PMMA plastic optic fiber. The detector package features an internal micro-lens and a precision-molded PBT housing to ensure efficient optical coupling with standard 1000µm core plastic fiber cable.

Application Highlights

The IF-D93 is suitable for low-speed optical links requiring high sensitivity. Triggering rates up to 1k are possible using the IF-D93 and a suitable LED source. Photodarlington transistor operation provide very high optical gain, eliminating the need for post amplification in many circuits. The integrated design of the IF-D93 makes it a simple, cost-effective solution in a variety of applications.
