ST-1MLAR2

The ST-1MLAR2 is designed as one kind of high sensitivity NPN silicon phototransistor that mounted in TO-18 type header with black epoxy encapsulation. With daylight filter the phototransistor is sensitive only to infrared rays. Features of the ST-23G are:(1)wide angular response;(2)durable;(3)high reliability in demanding environments;(4)two leads (collector, emitter) ST-1MLA;(5)three leads (collector emitter, base) ST-1MLB. And this device can be used in remote control sensors, card readers and optical switches applications.

The absolute maximum ratings of the ST-1MLAR2 can be summarized as:(1)C-E voltage: 40 V;(2)E-C voltage: 4 V;(3)collector current: 30 mA;(4)collector power dissipation: 100 mW;(5)storage temperature: -25 to +90 ;(6)storage temperature: -30 to +100 ;(7)soldering temperature: 260 .

And the electrical characteristics of this device can be concluded into several points:(1)collector dark current: 1 to 200 nA;(2)light current: 0.5 to 5.0 mA;(3)C-E saturation voltage: 0.2 to 0.4 V;(4)switching speeds rise time: 8 usec;(5)switching speeds fall time: 10 usec;(6)spectral sensitivity: 720 to 1050 nm;(7)peak wavelength: 940 nm;(8)half angle: +/- 70 deg.
