Latest surface-mount infrared receivers operate from -30C to +85C

Vishay has broadened its optoelectronics portfolio with the introduction of a new extended temperature option for its popular TSOP37xxx, TSOP57xxx, and TSSP57xxx series of infrared (IR) receivers and sensors in the surface-mount Belobog package. While the standard storage and operating temperature range for Vishay's standard IR receivers is -25C to +85C, devices with the 'E' option feature an extended storage temperature range of -40C to +110C and extended operating temperature range of 30C to +85C. All products in the Belobog series feature a floor life of 168 hours per MSL 3. The standard versions of the TSOP37xxx, TSOP57xxx, and TSSP57xxx IR receivers are designed for remote control applications such as digital still cameras, consumer televisions, and set-top boxes. With the extended storage and operating temperature ranges, the TSOP37xxxE, TSOP57xxxE, and TSSP57xxxE receivers provide a more robust package design for increased reliability in outdoor applications - including parking space sensors, light barrier systems, and in-car entertainment systems - that are exposed to wide daily temperature variations, and temperature extremes in northern and southern geographical locations. IR receivers in the Belobog package combine an ultra-low 0.8 mm profile with an extremely wide 150° angle of sensitivity. The receivers have no lens yet provide on-axis sensitivity equal to any surface-mount IR receiver on the market. At an off-axis angle of 45°, the devices retain 85 % of their on-axis sensitivity - much higher than receivers with a lens. To simplify designs, TSOP37xxxE, TSOP57xxxE, and TSSP57xxxE series receivers offer a photo detector and preamplifier circuit in a single epoxy package. The RoHS-compliant, halogen-free IR receivers offer a supply voltage from 2.5V to 5.5V, very low supply current down to 0.35mA at 3.3V, and improved immunity against ambient light, and they are insensitive to supply voltage and ripple noise.
