Malvern, Pa. −Vishay Intertechnology, Inc. has expanded its optoelectronics portfolio with the introduction of a high-power, high-speed 940 nm infrared (IR) emitter for gesture remote control applications. Offering high radiant power of 40 mW at 100 mA, the VSLB9530S is built on GaAIAs multi-quantum well (MQW) technology.
The VSLB9530S IR emitter is offered in a clear molded, leaded TELUX package with an oval lens designed to support an angle of half intensity of ± 18° in the vertical direction and ± 36° in the horizontal direction. The device's "unique angular distribution" and "excellent spectral matching with silicon photodetectors" makes it suitable for gesture remote control of televisions and gaming systems.
The TELUX package measures 7.62- x 7.62- x 4.6-mm and provides a low thermal resistance of 200 K/W. While standard IR emitters typically offer drive currents to 100 mA, the low thermal resistivity of the VSLB9530S allows continuous drive currents up to 150 mA, which pushes the achievable radiant intensity to 60 mW/sr at 150 mA, said Vishay. The device offers high modulation bandwidth of 24 MHz and is suitable for high pulse current operation.
The IR emitter offers fast switching speeds down to 15 ns, low forward voltage down to 1.31 V at 150 mA, and an operating temperature range from -40°C to +95°C. The device's wider angle in the horizontal view helps maintain position flexibility for users, while the narrower angle in the vertical plane focuses the distributed radiant intensity, said Vishay.
The VSLB9530S IR emitter is compatible with wave solder processes according to CECC 00802, and conforms to Vishay's "green" standards. It is also compliant to RoHS Directive 2011/65/EU, and halogen-free per JEDEC JS709A.
