LTV-354T-A

Lite On · Transistor, Photovoltaic Output Optoisolators · SOP-4-2.54mm

LTV-354T-A from Lite On, 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 Anode, Cathode passive AC input LED terminal (anode/cathode, either polarity) with forward current rated ±50 mA maximum and 70 mW input power dissipation.
2 Cathode, Anode passive AC input LED terminal (cathode/anode, either polarity) with forward current rated ±50 mA maximum and 70 mW input power dissipation.
3 Emitter passive Phototransistor emitter, with emitter-collector voltage rated 6 V maximum.
4 Collector passive Phototransistor collector, rated 35 V maximum collector-emitter voltage and 50 mA maximum collector current.
