What is VSLY5940 used for?

The datasheet lists CMOS-camera infrared illumination, high-speed IR data transmission, smoke-automatic fire detectors, and IR flash as applications.

What should engineers review before using VSLY5940?

Confirm the narrow ±3° half-intensity beam suits the optical geometry. Observe the 100 mA continuous forward-current limit, pulsed-current limits, 190 mW power-dissipation limit, and -40 °C to +85 °C operating range.

What is the pinout of VSLY5940?

Use the VSLY5940 datasheet for the official pinout diagram and pin names. In PartGenie, ask Datasheet AI about VSLY5940 pinout to locate pins, power rails, and interface signals before layout.
