Vishay Intertechnology, Inc. broadened its optoelectronics portfolio with the introduction of two new series of miniature infrared (IR) receiver modules for IR remote control applications in consumer products. Offered in the new Minimold package, Vishay Semiconductors TSOP33xxx and TSOP53xxx series devices deliver the same RF noise rejection as Minicast receivers, while surpassing the high optical performance of Mold package devices.

For products such as televisions, set-top boxes, air conditioners, and hi-fi audio systems, the devices released today provide high sensitivity with typical irradiance down to 0.08 mW/m2 at 0 for the TSOP33xxx series and 0.12 mW/m2 for the TSOP53xxx series. While the 0° sensitivity is the same as for the Mold package, the Minimold package exhibits higher sensitivities than the Mold device at all off-angles up to 45°. The Minimold package also comes with the proven “F” option for an enhanced optical filter against out-of-band optical noise.

To simplify designs, TSOP33xxx and TSOP53xxx series devices feature a photo detector, preamplifier circuit, and IR filter in a single 3-pin epoxy package. The receivers offer a supply voltage from 2.5 V to 5.5 V; very low supply current of 0.35 mA typical for the TSOP33xxx series and 0.7 mA for the TSOP53xxx series; transmission range up to 45 meters; and carrier frequencies from 30 kHz to 56 kHz. The devices provide improved immunity against ambient light and are insensitive to supply voltage variations and ripple noise.

The IR receivers are offered in five automatic gain control (AGC) versions for short and long burst codes. The TSOP331xx, TSOP332xx, TSOP531xx, and TSOP532xx provide legacy compatibility with all common IR control data formats. The TSOP333xx, TSOP334xx, TSOP533xx, and TSOP534xx are ideal for all remote control applications and suppress spurious pulses from energy-saving lamps and Wi-Fi sources, in addition to continuously transmitted data signals.
