TLP818

The TLP818  is designed as a photointerrupter with a dustproof cover. It is not greatly influency by dust because there is no powered dust accumulation at detecting slit part.

TLP818 has eight features. (1)Built in dustproof cover. (2)Snap-in monting type (1.6mm thickness of PCB). (3)Gap 5mm. (4)Resulution is slit width 0.5mm. (5)High current ransfer ratio which would be min 2.5%. (6)Fast response speed which would be typ 6us. (7)It is not greatly influenced by disturbance beams of indoor lighting because detector has visible light cut resin. (8)Material of the package is polycarbonate. Those are all the main features.

Some absolute maximum ratings of TLP818 have been concluded into several points as follow. (1)Its forward current would be 50mA. (2)Its forward current derating would be -0.33mA/°C. (3)Reverse voltage would be 5V. (4)Its collector to emitter voltage would be 35V. (5)Its emitter to collector voltage would be 5V. (6)Its collector power dissipation would be 75mW. (7)Its collector power dissipation derating would be -1mA/°C. (8)Its collector current would be 50mA. (9)Its operating temperature range would be from -25°C to 85°C. (10)Its storage temperature range would be from -40°C to 100°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 TLP818 are concluded as follow. (1)Its forward voltage would be min 1V and typ 1.15V and max 1.3V. (2)Its reverse current would be max 10uA. (3)Its peak emission wavelength would be typ 940nm. (4)Its dark current would be max 0.1uA. (5)Its peak sensitivity wavelength would be typ 870nm. (6)Its current transfer ratio would be min 2.5% and max 32%. (7)Its collector to emitter saturation voltage would be typ 0.15V and max 0.4V. (8)Its rise and fall time would be typ 6us.
