MOC8112 is listed in the Transistor, Photovoltaic Output Optoisolators range at ChipApex. The manufacturer field lists Isocom Components 2004 LTD. Its product description is OPTOISOLTR 5.3KV 1CH TRANS 6-DIP. Review the specifications below when checking this part for your BOM.
The MOC8112 is a non-base lead optically coupled isolator manufactured by Isocom Components. It integrates an infrared light emitting diode and an NPN silicon phototransistor within a standard 6-pin dual in-line plastic package. The device features a base pin that remains unconnected, a design choice intended to enhance noise immunity in high electromagnetic interference environments. It provides a high isolation voltage of 5.3kVRMS and 7.5kVPK between the input and output circuits.
Verify the specific suffix (e.g., G, SM, SMT&R) against the required lead spread or mounting style. Confirm RoHS compliance status and UL/VDE recognition numbers match the target application's regulatory requirements. Ensure the datasheet version corresponds to the exact manufacturing batch specifications.
Select this component when high noise immunity is critical due to the unconnected base terminal. Verify that the 6-pin DIP form factor fits the PCB layout constraints. Ensure the operating temperature range and isolation voltage ratings meet the system's electrical safety standards.
This part belongs to the MOC8101-8105 series of optocouplers from Isocom Components. These devices are designed as general-purpose isolators with specific attention to EMI resistance through their unique internal transistor structure.
Cross-reference with other manufacturers' non-base lead phototransistor optocouplers. Verify pinout compatibility and electrical parameters such as CTR and isolation voltage before substitution.
