FIREFLY™ E1608 Infrared Emitters

ams OSRAM FIREFLY E1608 CN DELSS1.27 and CN DELSS2.27 are infrared (IR) light-emitting diodes (LEDs) that represent a significant expansion of the company's vital sign monitoring and sensing portfolio. These IR emitters are part of the acclaimed FIREFLY E1608 family, known for combining high reliability with one of the smallest industry-standard footprints. The compact dimensions of just 1.6 mm x 0.8 mm x 0.6 mm provide design engineers with superior flexibility, enabling seamless integration into space-constrained devices such as fitness trackers, true wireless stereo (TWS) earbuds, smartwatches, and a variety of automotive systems.

The CN DELSS1.27 and CN DELSS2.27 variants are specifically designed to operate in the infrared spectrum (IR greater than 800 nm), making them the ideal choice for applications requiring precise near-infrared light sources. Their outstanding performance is perfectly suited for complex sensing tasks like SpO₂ (pulse oximetry) measurements and proximity sensing. Furthermore, the CN DELSS2.27 model is engineered with an increased operating temperature range up to +110°C and features the AEC-Q102 automotive qualification, making it perfectly suited for robust automotive applications, such as integration into rain sensors. Utilizing a white surface-mount technology (SMT) package with a colorless clear resin and offering a typical radiation angle of 120° (Lambertian emitter), these devices ensure excellent light coupling and reliable performance across their target applications. Their proven package concept guarantees high reliability, positioning them as a top-tier choice for next-generation portable electronics and automotive sensing solutions.
