Infrared discretes serve high-speed, high-power applications

25 October 2000 Opto-Electronics

Four new series of discrete infrared (IR) components, including both emitting and receiving devices have been released by Vishay Intertechnology. The devices are the first from Vishay in a miniaturised surface-mount package with an integrated lens measuring just 2,5 by 2,0 mm with a 2,8 mm height profile. Applications for the new devices will range from steering wheel encoders and window controls in automobiles to IrDA-compatible data transmission in PDAs and notebook computers.

For photo interrupter, miniature light barrier, optical counter and infrared sensor applications, Vishay is introducing the 950 nm TEMT10xx photo transistor and TSML10xx infrared emitter series. The TEMT100xx photo transistors feature high sensitivity, a 2 µs turn-on time, plus a daylight filter that reduces the effects of near-IR radiation. The TSML10xx emitters provides an extra-high radiant power of 35 mW and a typical radiant intensity of up to 300 mW per steradian - yet consume about the same power as standard-performance devices, with a typical forward voltage of just 1,35 V.

For IrDA-compliant data transmission, high-speed optical encoder systems and fibre-optic modules, Vishay is introducing two new 870 nm high-speed infrared series. New TEMD10xx photo PIN diodes provide fast 4 ns rise and fall times with high sensitivity enabled by a ±15° viewing angle and a 0,25 mm squared radiant sensitive area. An integrated daylight filter reduces the effects of natural light. For high-speed infrared emitting, Vishay is introducing the new TSMF10xx. These new devices combine high-performance 30 ns rise and fall times with radiant power of 35 mW, yet like the TSML10xx series consume no more power than conventional devices, with forward voltage of just 1,4 V.

All four new device series are offered with four lead configuration options - gull-wing, reverse gull-wing, yoke and axial - and supplied in tape and reel form for high-speed assembly.
