TLN208

The TLN208 is designed as toshiba LED lamp. Typical applications include infrared light emission diode for still camera and light source for auto focus.

TLN208 has six features. (1)Optical radiation of current confining LED chip is condensed by a resin lens. (2)Large output. (3)Effective emission diameter is 344um. (4)Optical output can be radiated efficiently in a solid angle 0.685sr. (5)Proper forward voltage for 2 cells. (6)Optical output vs temperature characteristic is almost constant in case of constant forward voltage drive system. Those are all the main features.

Some absolute maximum ratings of TLN208 have been concluded into several points as follow. (1)Its forward current would be 50mA. (2)Pulse forward current would be 400mA. (3)Its reverse voltage would be 1V. (4)Its operating temperature range would be from -25°C to 60°C. (5)Its storage temperature range would be from -40°C to 90°C. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of TLN208 are concluded as follow. (1)Its forward voltage would be typ 1.35V. (2)Its pulse forward voltage would be typ 1.75V and max 1.95V. (3)Its reverse current would be max 100uA. (4)Its effective emission spot diameter would be typ 344um. (5)Its radiation flux would be min 7mW and typ 12mW. (6)Its half value angle would be typ 54°. (7)Its peak emission wavelength would be typ 875nm. (8)Its spectral line half width would be typ 40nm.

It should be noted that toshiba is continually working to improve the quality and the reliability of its products. Nevertheless, semiconductor devices in general can malfunction or fail due to their inherent electrical sensitivity and vulnerability to physical stress. It is the responsibility of the users, when utilizing these products, to observe standards of safety, and to avoid situations in which a malfunction or failure of a product could cause loss of human life, bodily injury or damage to property. And so on. If you have any question or suggestion or want to know more information of TLN208 please contact us for details. Thank you!
