Vishay releases high-power, high-speed 940nm IR emitter for gesture remote control applications

Vishay Intertechnology Inc of Malvern, PA, USA has introduced a new aluminium gallium arsenide (AlGaAs) based, high-power, high-speed 940nm infrared emitter for gesture remote control applications. Offering high radiant power of 40mW at 100mA, the VSLB9530S 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, says the firm.

The TELUX package of the VSLB9530S measures 7.62mm by 7.62mm by 4.6mm and provides a low thermal resistance of 200K/W. While standard IR emitters typically offer drive currents to 100mA, the low thermal resistivity of the VSLB9530S allows continuous drive currents up to 150mA, which pushes the achievable radiant intensity to 60mW/sr at 150mA. The device offers high modulation bandwidth of 24MHz and is suitable for high pulse current operation.

The infrared emitter offers fast switching speeds down to 15ns, low forward voltage down to 1.31V at 150mA, and an operating temperature range from -40°C to +95°C. Compatible with wave solder processes according to CECC 00802, the VSLB9530 is compliant to RoHS Directive 2011/65/EU, halogen-free per JEDEC JS709A, and conforms to Vishay’s “Green” standards.

Samples and production quantities are available now, with lead times of six to eight weeks for large orders.
