CTM3053 from CT Micro International, 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 | Anode of the GaAs infrared LED input; forward current max 60 mA, VF max 1.5 V at IF=10mA, reverse voltage max 6 V. |
| 2 | Cathode | passive | Cathode of the GaAs infrared LED input; for the CTM3053 the input trigger current IFT is max 5 mA. |
| 3 | MT2 | passive | Main terminal 2 of the random-phase phototriac output; off-state voltage rated 600 V. |
| 4 | MT1 | passive | Main terminal 1 of the random-phase phototriac output; peak repetitive surge current 1 A. |
