TLP907

The features of TLP907/TLP907(LB) can be summarized as (1)detection of start and end marks on video and audio tape; (2)detection of vcr reel rotation; (3)detection of index write-protect and; (4)presence of disk for floppy disk drive; (5)timing detection in electronic printers and typewriters; (6)reading of camera film information (dx code).

The absolute maximum ratings of TLP907/TLP907(LB) are (1)forward current(IF): 50 mA ; (2)forward current derating (Ta>25°C)(dIF /°C): -067 rnA /°C; (3)pulse forward current (Note 1: pulse wigth100s, repetitive frequency=100Hz)(IFP): 400 mA ; (4)reverse voltage(VR): 5V; (5)collector-emitter voltage(VCEO): 30V; (6)emitter-collector voltage (VECO): 5V; (7)collector power dissipation(PC): 50 mW ; (8)collector power dissipation derating (Ta>25°C) (dP/°C):-067 mW/°C ; (9)collector current(IC): 20 mA ; (10)operating temperature range(Topr): -25 to 85°C; (11)storage temperature range(Tstg): -30 to 10°C.

When forming the leads, be careful not to apply stress to the main body of the TLP907 (the resin part). Soldering must be performed after the leads have been formed. Collector current falls over time due to the current which flows in the infrared LED. When designing a circuit, take into account this change in conversion efficiency over time. The ratio fluctuation in collector current to fluctuation in infrared LED optical output is 1:1.
