TLP1020

The TLP1020 is designed as toshiba photointerrupter which has a GaAs infrared LED with high sensitive and high gain silicon photo IC.

TLP1020 has ten features. (1)Printed wiring board direct mounting type (with a locating pin). (2)Gap 2.2mm. (3)High resolution slit width 0.2 x 2.0mm (the oblong slit). (4)Digital output (open collector). (5)Built-in schmitt circuit. (6)Threshold input current is max 10mA at Ta=25°C. (7)Operating supply voltage is from 4.5V to 17V. (8)Directly connectable to TTL, LSTTL and CMOS. (9)Fast response speed which means 3us for tpLH and 6us for tpHL. (10)Detector side is of visible light cut type. Those are all the main features.

Some absolute maximum ratings of TLP1020 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)Its reverse voltage would be 5V. (4)Its supply voltage would be 17V. (5)Its output voltage would be 30V. (6)Its output current would be 50mA. (7)Its power dissipation would be 250mW. (8)Its power dissipation derating would be -3.33mW/°C. (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. (11)Its soldering temperature would be 260°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 TLP1020 are concluded as follow. (1)Its forward current would be min 1.00V and typ 1.15V and max 1.30V. (2)Its reverse current would be max 10uA. (3)Its peak emitter wavelength would be typ 940nm. (4)Its low level supply current would be max 5.0mA. (5)Its high level supply current would be max 3.0mA. (6)Its low level output voltage would be typ 0.07V and max 0.3V. (7)Its high level output current would be max 15uA. (8)Its peak sensitivity wavelength would be typ 900nm. (9)Its threshold input current high to low would be max 10mA. And so on. If you have any question or suggestion or want to know more information of TLP1020 please contact us for details. Thank you!
