Lite On · Transistor, Photovoltaic Output Optoisolators · SOP-4-2.54mm
LTV-356T 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 is rated at 50 mA maximum (IF) and VF is 1.2 V typ at IF=20mA. |
| 2 | Cathode | passive | LED cathode of the input side; reverse voltage is rated at 6 V maximum (VR). |
| 3 | Emitter | passive | Phototransistor emitter of the output side; emitter-collector voltage is rated at 6 V maximum (VECO). |
| 4 | Collector | passive | Phototransistor collector of the output side; collector-emitter voltage is rated at 80 V maximum (VCEO) and collector current at 50 mA maximum (IC). |
