IR receiver modules save space

Broadening its optoelectronics portfolio, Vishay Semiconductors introduces two series of miniature IR receiver modules for remote control applications. To save space in consumer products, the TSOP39xxx and TSOP59xxx devices are the industry’s first native top-view IR receivers in a through-hole package, claims the company.

By eliminating the need for a lead bend, typically used to modify side-view packages for top-view receivers, the PCB space required in set-top boxes, air conditioners, and high-end audio systems is reduced. The two-lens design offers high sensitivity, and the TSOP39xxx and TSOP59xxx offer typical irradiance down to 0.08mW/m² and 0.20mW/m², respectively.

To simplify designs, the IR receivers have a photo-detector, pre-amplifier circuit, and IR filter in a single, four-pin epoxy package. The devices offer a supply voltage from 2.5 to 5.5V, a low supply current of 0.35mA typical (TSOP39xxx) and 0.7mA (TSOP59xxx) and a transmission range up to 45m. Carrier frequencies are 30 to 56kHz. According to the company, the receivers provide improved immunity against ambient light and are insensitive to supply voltage variations and ripple noise.

Both are offered in four automatic gain control (AGC) versions for short and long burst codes. All receivers are RoHS-compliant and halogen-free.
