PS4601

The PS4601 is designed as one kind of one piece photo interrupters which contains a GaAs LED and NPN photo transistor in one molded package.

PS4601 has three features. (1)Ultra small and thin package (width is 2.5mm typ). (2)High speed response (t=9us typ). (3)Single in-line package 4 pin. Those are all the main features.

Some PS4601 absolute maximum ratings have been concluded into several points as follow. (1)Its diode reverse voltage would be 5.0V. (2)Its forward current would be 50mA. (3)Its diode power dissipation would be 100mW. (4)Its transistor collector to emitter voltage would be 30V. (5)Its collector current would be 40mA. (6)Its transistor power dissipation would be 100mW. (7)Its storage temperature range would be from -40°C to 100°C. (8)Its operating temperature range would be from -20°C to 80°C. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some PS4601 electrical characteristics are concluded as follow. (1)Its forward voltage would be typ 1.1V and max 1.4V with conditions of If=10mA. (2)Its reverse current would be max 10uA with conditions of Vr=5.0V. (3)Its junction capacitance would be typ 30pF with conditions of V=0 and f=1MHz. (4)Its collector to emitter dark current would be max 100nA with conditions of Vce=10V and If=0. (5)Its output current would be min 150uA and typ 400uA with conditions of If=10mA and Vce=100uA. (6)Its collector saturation voltage would be max 0.3V with conditions of If=10mA and Ic-100uA. (7)Its collector leak current ratio would be typ 0.5% with conditions of If=10mA and Vce=2.0V shielded. (8)Its rise time would be typ 9us. (9)Its fall time would be typ 12us. And so on. At present we have not so much information about this IC and we would try hard to get more information about it.
