Lite On · Transistor, Photovoltaic Output Optoisolators · SOP-4-2.54mm
LTV-357T-D 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 is rated 50 mA max, with VF typically 1.2 V (1.4 V max) at IF=20 mA. |
| 2 | Cathode | passive | LED cathode of the input side; reverse voltage VR is rated 6 V max. |
| 3 | Emitter | passive | Phototransistor emitter on the output side; emitter-collector voltage VECO is rated 6 V max. |
| 4 | Collector | passive | Phototransistor collector on the output side; collector-emitter voltage VCEO is rated 35 V max and collector current IC 50 mA max. |
