# MOC3053M

**AOTE** · Triac, SCR Output Optoisolators · DIP-6

MOC3053M from AOTE, in a DIP-6. 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 of the input emitter, driven with a recommended forward current of 5 mA to 15 mA (absolute maximum 60 mA). |
| 2 | Cathode | input | LED cathode of the input emitter; reverse voltage must not exceed 6 V. |
| 3 | NC | unconnected | No internal connection. |
| 4 | Terminal | passive | Main triac output terminal, rated for an off-state voltage VDRM of 600 V (MOC305X) and an on-state current of 100 mA RMS. |
| 5 | NC | unconnected | No internal connection (substrate pin on the triac side, not for use). |
| 6 | Terminal | passive | Main triac output terminal, rated for an off-state voltage VDRM of 600 V (MOC305X) and an on-state current of 100 mA RMS. |
