Miniature surface-mount top-view near-infrared LEDs

Rohm has introduced six miniature surface-mount top-view near-infrared LEDs.

There are three packages: one measures 1 x 0.6mm and is only 0.2mm thick including a layer of encapsulation. Emission is 2.8mW/sr at 30mA.

The other two measure 1.6 x 0.8mm and have either a lensed top (1.24mm tall, 5mW/sr at 20mA), or a flat top (1.06mm tall, 1.9mW/sr at 20mA) for a wider beam.

Each package has two wavelength options: SML-P14RW (860nm) and SML-P14R3W (940nm) are the tiny ones, CSL0902RT (850nm) and CSL0902R3T (940nm) have the lensed top, and CSL1002RT (850nm) and CSL1002R3T (940nm) have the woder beam.


“850nm is ideal for photo-transistors and camera sensors, making it suitable for high-sensitivity applications such as eye tracking and object detection in virtual and augmented reality,” said the company. “940nm is less affected by sunlight and does not appear red when emitting light, making it suitable for motion sensors. It is also used in biosensing applications such as pulse oximeters to measure blood flow and oxygen saturation.”

Earlier this year, Rohm announced miniature surface-mount THz (320GHz) transmiters and receivers
