TCLT1007

Vishay Intertech · Transistor, Photovoltaic Output Optoisolators · SOP-4-2.54mm

TCLT1007 from Vishay Intertech, in a SOP-4-2.54mm. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	A	passive	Anode of the gallium arsenide infrared-emitting diode; the input is rated for forward current IF of 60 mA maximum and reverse voltage VR of 6 V maximum.
2	C	passive	Cathode of the gallium arsenide infrared-emitting diode; the input is rated for forward current IF of 60 mA maximum and reverse voltage VR of 6 V maximum.
3	E	passive	Emitter of the phototransistor output; the emitter-collector voltage VECO is rated 7 V maximum.
4	C	passive	Collector of the phototransistor output; the collector-emitter voltage VCEO is rated 70 V maximum and the collector current IC is rated 50 mA maximum.
