Vishay releases IR receivers for remote control with height of 0.8 mm

Flat-panel LCD and plasma TV displays continue to get thinner, which means that the components inside them need to get thinner as well, without compromising performance. But it”s not just TV sets that need low-profile infrared receivers. Set-top boxes, stereo systems, and in-room air-conditioners also need to accommodate IR receivers within a highly constrained area.

Vishay”s TSOP57x IR receivers are just 0.8 mm — thinner than a house key. The new TSOP57x IR receivers have no lens, yet they provide on-axis sensitivity equal to any surface-mount receiver on the market.

At an off-axis angle of 45°, the receivers” sensitivity is much better than devices with a lens, retaining 85 % of their on-axis sensitivity. Because remote control receivers are placed behind cosmetic windows that typically absorb some infrared light, this high sensitivity allows the TSOP57x series to outperform other surface-mount receivers on the market.

The receivers feature Vishay”s intelligent automatic gain control (AGC), providing noise suppression in versions that include AGC2, -3, -4, and -5. They have peak sensitivity of 940 nm and are available in modulation frequencies of 36 kHz, 38 kHz, 40 kHz, and 56 kHz.

The devices feature an environmentally friendly “green” construction compliant to RoHS Directive 2011/65/EU and in accordance to WEEE 2002/96/EC.
