Lite-On · Pre-ordered Products · SOP-4-2.54mm

LTV-357T 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 passive LED anode of the input side; forward current IF max 50 mA, reverse voltage VR max 6 V, VF typ 1.2 V at IF=20 mA.
2 Cathode passive LED cathode of the input side; return for the forward current (IF max 50 mA).
3 Emitter passive Phototransistor emitter; emitter-collector voltage VECO max 6 V.
4 Collector passive Phototransistor collector; VCEO max 35 V and collector current IC max 50 mA.
