Vishay releases new high-power, high-speed infrared transmitter

Pennsylvania, MALVERN — April 1, 2013 — A few days ago, Vishay Intertechnology, Inc. (NYSE stock code: VSH) announced the launch of high-power, wide-angle convex lenses with gull-wing, inverted gull-wing, and side-view surface mount packages. High-speed 850nm, 890nm and 940nm infrared emitters --- VSMY2853, VSMF2893, VSMB2943 and VSMB2948, expand their optoelectronic product portfolio.

The VSMY2853, VSMF2893, VSMB2943, and VSMB2948 series devices contain a lens with a suitable radius, which can provide ± 25 ° and ± 28 ° half-power angles. At a drive current of 100 mA, the typical luminous intensity of the device ranges from 20 mW / sr to 35 mW / sr. The infrared transmitter is packaged in a small size top-view 2.3mm x 2.3mm x 2.5mm gull-wing and inverted gull-wing package, and a 2.3mm x 2.55mm x 2.3mm side-view package, which saves space compared to the PLCC2 solution.

The device adopts GaAIAs surface emitting chip (VSMY2853), double heterogeneous (VSMF2893) and multi-quantum well (VSMB2943, VSMB2948) technology, suitable for flat infrared touch panel, 3D TV shutter glasses synchronization, remote control, light curtain, grating External emission sources for instrumentation systems and proximity detection applications. VSMB2943 and VSMF2893 have passed AEC-Q101 certification and can be used in automobiles.

The switching speed of the infrared transmitter released today is only 10ns, the forward voltage drop at 100mA is 1.35V, and the operating temperature is −40 ℃ ~ + 85 ℃. The device can be stored in the production workshop for 4 weeks, and the moisture sensitivity level (MSL) reaches level 2 specified in J-STD-020. The VSMY2853, VSMF2893, VSMB2943 and VSMB2948 series comply with the RoHS directive 2011/65 / EU, meet the halogen-free requirements of per JEDEC JS709A and Vishay's "green" standards.
