KMOC3052

Cosmo Electronics · Triac, SCR Output Optoisolators · DIP-5

KMOC3052 from Cosmo Electronics, in a DIP-5. 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 input LED; input forward current IF is rated at 50 mA max, peak forward current IFM at 1 A, and reverse voltage VR at 6 V.
2	Cathode	passive	Cathode of the GaAs infrared input LED, which must stay within the 6 V reverse voltage rating (VR).
3	NC	unconnected	Marked NC in the datasheet schematic (no connection).
4	Main terminal	passive	Main terminal of the non-zero-crossing bilateral TRIAC output switch, rated for 600 VPEAK off-state voltage (VDRM) and 100 mA on-state RMS current IT(RMS).
6	Main terminal	passive	Main terminal of the non-zero-crossing bilateral TRIAC output switch, rated for 600 VPEAK off-state voltage (VDRM) and 100 mA on-state RMS current IT(RMS).
