Vishay Intertechnology offer high remote control performance for Flat-Panel TVs and Monitors

 Vishay Intertechnology, has broadened its optoelectronics portfolio with the introduction of two new series of miniature infrared (IR) receiver modules for IR remote control applications in flat-panel TVs and monitors. For front mounting in the tight 3 mm frames of these products, Vishay Semiconductors TSOP39xxxTR1 and TSOP59xxxTR1 series devices are the industry’s first to be offered in the TVCastSMD side-view, winged, surface-mount package with an ultra low height of 2.6 mm.

  For remote control in modern flat-panel TVs, three optical components — an IR receiver, red LED, and ambient light sensor — must either fit in the narrow frame or have an optical connection to the front from the back via a light pipe, which reduces the range for the IR receiver. The TVCastSMD package of the TSOP39xxxTR1 and TSOP59xxxTR1series is designed to be mounted on a PCB with a side-view orientation. The board is then inserted into the frame, allowing for placement near the front of the frame for superior remote control performance.

  To simplify designs, the devices released recently feature a photodetector, preamplifier circuit, and IR filter in a single 4-pin epoxy package. Featuring a two-lens design for high sensitivity, the IR receivers offer typical irradiance down to 0.08 mW/m² and 0.20 mW/m², respectively. The components feature a supply voltage from 2.5 V to 5.5 V; very low supply current of 0.35 mA typical for the TSOP39xxxTR1 series and 0.7 mA for the TSOP59xxxTR1 series; transmission range up to 45 meters; and carrier frequencies from 36 kHz to 56 kHz.

  TSOP39xxxTR1 and TSOP59xxxTR1 series devices provide improved immunity against ambient light, are insensitive to supply voltage variations and ripple noise, and are offered in four automatic gain control (AGC) versions for short and long burst codes. All receivers are RoHS-compliant, halogen-free, and Vishay Green.
