Native top-view IR receivers in through-hole package save space in consumer products

Vishay Intertechnology has broadened its optoelectronics portfolio with the introduction of two new series of miniature IR receiver modules for IR remote control applications. To save space in consumer products, the Vishay Semiconductors TSOP39xxx and TSOP59xxx series devices are claimed to be 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-degree 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 devices offer typical irradiance down to 0.08mW/m² and 0.2mW/m², respectively. To simplify designs, the IR receivers feature a photodetector, preamplifier circuit, and IR filter in a single four-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 45m; 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. The 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.
