Vishay’s TSOP85.. Series of SMD IR Receiver Modules Features Industry’s Highest Sensitivity-to-Size Ratio in Compact Top- or Side-View Package

Vishay Intertechnology, Inc. (NYSE: VSH) today released a new series of surface-mount infrared receiver modules that offer the industry's highest sensitivity-to-size ratio.

Designed for long-range operation in infrared remote control, data transmission, and light barrier applications, the new TSOP85.. series is intended for use in portable systems requiring ultra-small component profiles. Typical end products include small handheld devices, such as laptops, digicams and video equipment, music and video players, and navigation equipment.

In optical modules, decreasing the package size results in a reduction of lens size, which therefore reduces sensitivity and range. The TSOP85.. series, however, neutralizes this effect through the addition of a second lens and photodiode. In addition, the two-lens arrangement achieves a broader receiving angle than can be achieved with only one lens.

The TSOP85.. receiver modules combine two photo detectors and a preamplifier in a top- or side-view surface mount package. The devices offer a compact footprint with a height of 3.3 mm in top view and only 2.74 mm in side view, making them suitable for applications where space saving is a primary consideration.

In addition to being specified for a broad supply voltage range of 2.7 V to 5.5 V, the TSOP85.. series contains versions capable of operating with short-burst ( 6 cycles/burst) transmission codes and data rates up to 4000 bit/s, and versions exhibiting immunity to even severe environmental noise.

All devices in the series are available in seven standard carrier frequencies from 30 kHz up to 56 kHz and contain internal Automatic Gain Control (AGC) circuitry, providing enhanced immunity against optical noise and other ambient disturbances.

Samples and production quantities of the TSOP85.. infrared receiver modules are available now, with lead times of six weeks for larger orders.
