Vishay Intertechnology Unveils New Infrared Receivers

July 11, 2014

Vishay Intertechnology has broadened its optoelectronics portfolio with the release of two new miniaturized infrared (IR) receivers designed specifically for low-speed data transmission.

According to a release, the TSDP34138/56 and TSDP34338/56 are optimized for low-complexity, low-cost signaling in metering, sensor, automation, and gaming applications.

Specified for operation from 2.5 V to 5.5 V, with a low 0.35 mA supply current at 3.3 V, the Vishay Semiconductors receivers released each consist of a photodiode and preamplifier assembled on a lead frame. The devices' epoxy package - measuring 6.0 mm by 6.9 mm by 5.6 mm - acts as an IR band pass filter for use with inexpensive 940 nm IR LEDs.

Data transmission is a central element in a wide range of electronics. As an alternative to radio frequency (RF) transmission, the use of IR components such as the TSDP34138/56 and TSDP34338/56 simplifies designs, lowers costs, and eliminates the need to obtain regulatory approvals. In addition, by requiring line-of-sight, IR enhances privacy and minimizes interference with adjacent systems.

Vishay Intertechnology, Inc., is a manufacturer of discrete semiconductors (diodes, MOSFETs, and infrared optoelectronics) and passive electronic components (resistors, inductors, and capacitors).
