Optocouplers Specified to Operate at 110C

November 12, 2014 By admin Comments are Off

Everlight Electronics Co. Ltd. is showcases its broad and growing infrared portfolio at electronica 2014 that includes infrared LEDs, photo transistors and photo diodes, infrared receiver modules, optical sensors, photocouplers and high speed couplers. A particular attention this year will be given to three new high performance optocouplers EL617, EL101X and EL121N that combine a high breakdown voltage of 80V with a wide operating temperature range from -55 to 110 degrees C which enhances system reliability.

EL617 and EL101X have a high isolation voltage of 5000 Vrms for improved insulation characteristics and a creepage distance of more than 8mm which offer an advantageous combination of key specifications sought after by power supply designers. The EL121N with 3,750 Vrms targets dc-dc converters. Other applications include programmable controllers, measuring instruments, telecommunication equipment, home appliances and for signal transmission between circuits of different potentials and impedances. All three optocouplers are Pb-free, RoHS-compliant and VDE approved. Sampling and technical support are available now (upon request). Mass production starts in Q4/2014.

Only recently, Everlight also introduced HIR C19D, a 855nm high-power infrared LED with low thermal resistance of 11 degrees C/W and a high radiant intensity of 350mW/sr at 700mA especially suited for CCD cameras, night guard security and other discrete surveillance systems. A viewing angle of 90° provides for an excellent illumination of the area under observation. The Pb free 3W high-power IRLED device is offered in a miniature 3.5 x 3.5 x 2.36 mm SMD package molded in a water clear silicone with spherical top view lens, and a ceramic PCB housing for low thermal resistance.

Another infrared novelty is Everlight’s ultra-thin 940nm top-view infrared LED IR92-01C in a miniature small 2(L)x1.4(W)x0.7(H) mm MIDLED package, announced earlier this year. With a low forward voltage of 1.3 V at 20mA, a high output power of 25mW/sr at 70mA and a narrow viewing angle of 45 degrees for even higher output intensity without lens, Everlight’s IR92-01C Series is suited for any kind of IR data transmission like remote controls, proximity and optical touch sensors and high-tech touch panels. However, with a thickness of only 0.7mm this small SMD device is especially suited for IR applications like tablets, smart phones, and more where high power output, narrow beam angle or space constraints are of major concern.
