IR receivers save space in consumer products
To broaden its optoelectronics portfolio, Vishay Intertechnology has introduced two new series of miniature infrared (IR) receiver modules for IR remote control applications. To save space in consumer products, the Vishay Semiconductors TSOP39xxx and TSOP59xxx series devices are the industry's first native top-view IR receivers in a through-hole package.
To accommodate applications requiring top-view IR receivers, side-view packages are typically modified with a 90° lead bend.
By eliminating the need for a lead bend, the devices released today reduce the PCB space requirement in products such as set-top boxes, air conditioners, and high-end audio systems.
Featuring a two-lens design for high sensitivity, the TSOP39xxx and TSOP59xxx offer typical irradiance down to 0.08mW/m² and 0.20mW/m², respectively.
To simplify designs, the IR receivers feature a photodetector, preamplifier circuit, and IR filter in a single 4-pin epoxy package.
The devices offer a supply voltage from 2.5V to 5.5V; very low supply current of 0.35mA typical for the TSOP39xxx series and 0.7mA for the TSOP59xxx series; transmission range up to 45 meters; and carrier frequencies from 30kHz to 56kHz.
The receivers provide improved immunity against ambient light and are insensitive to supply voltage variations and ripple noise.
TSOP39xxx and TSOP59xxx series devices 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.
Samples and production quantities of the TSOP39xxx and TSOP59xxx series are available now, with lead times of four weeks.
