UMW · Transistor, Photovoltaic Output Optoisolators · SOP-4-2.54mm
LTV-1008 from UMW, 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 | input | Anode of the AlGaAs infrared emitting diode, rated for forward current IF 60 mA, peak forward current 1 A (100 µs pulse, 100 Hz), and reverse voltage VR 6 V. |
| 2 | Cathode | passive | Cathode of the AlGaAs infrared emitting diode, sharing the input ratings of IF 60 mA, IFP 1 A (100 µs pulse, 100 Hz) and VR 6 V. |
| 3 | Emitter | passive | Emitter of the silicon phototransistor output, with emitter-collector voltage limit VECO 7 V. |
| 4 | Collector | output | Collector of the silicon phototransistor output, with limits of collector-emitter voltage VCEO 80 V, collector current IC 50 mA and output power dissipation PO 150 mW. |
