INFRARED EMITTERS and PHOTO DETECTORS Optoelectronics – Small Low-Profile Package – 3 x 2 x 1 (mm) VSMB10940, VSMG10850, VEMD10940F Low-Profile, Surface-Mount Side Lookers 1 mm Height, Side-view Infrared Emitters and Photo PIN Diodes Vishay’s 1 mm height emitters and detector have the best performance on the market. The emitters have the highest radiant intensity and feature the highest DC operating current up to 52 °C. At a 40 °C ambient temperature, the radiant intensity of the Vishay part is higher than the competing emitters by more than a factor of 2. The photo PIN diode has the lowest dark current, which results in the best signal-to-noise ratio.

The VSMB10940 has a peak intensity of 940 nm while the VSMG10850 peaks at 850 nm. Both emitters provide a radiant intensity of typically 1 mW/sr at 20 mA drive current. The VEMD10940F has a peak sensitivity of 920 nm and is optimized to maintain over 95 % sensitivity for the wavelength range of 840 nm to 970 nm. Therefore, it is ideally matched to both emitters. The VEMD10940F includes a filter to block visible light and provides a typical photo current of 3 µA given an irradiance of 1 mW/cm2, Vr = 5 V, λ = 950 nm.
