EL3H7D from AOTE, in a SSOP-4. 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 | LED anode with maximum forward current IF=50A and peak forward current IFP=1000A (1μs pulse). |
| 2 | Cathode | power_in | LED cathode with maximum reverse voltage VR=6V and power dissipation PD=70W. |
| 3 | Emitter | power_in | Phototransistor emitter with maximum emitter-collector voltage VECO=7V. |
| 4 | Collector | output | Phototransistor collector with maximum collector current IC=50A and collector-emitter voltage VCEO=80V. |

Package_SO:SSOP-4_4.4x2.6mm_P1.27mm - 3D model: SSOP-4, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 1.75 mm nominal SSOP height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
