MOC8108SM is listed in the Transistor, Photovoltaic Output Optoisolators range at ChipApex. The manufacturer field lists Isocom Components 2004 LTD. Its product description is OPTOISOLATOR 5.3KV 1CH TRANS. Review the specifications below when checking this part for your BOM.
The MOC8108SM is a surface-mount phototransistor optocoupler from the ISP series by Isocom Components. It features a single channel with an infrared LED input and NPN silicon phototransistor output in a 4-pin DIP package. Key electrical parameters include a maximum forward voltage of 1.4V, isolation voltage of 5.3kVrms, typical rise time of 4μs, and typical fall time of 3μs. The current transfer ratio ranges from a minimum of 0.2% to a maximum of 3%. Operating temperature spans -30°C to 100°C.
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm datasheet revisions match specific production batches. Check for UL recognition and VDE approval status relevant to target market regulations. Ensure packaging integrity matches surface-mount requirements.
Select this component when surface-mount technology is required for single-channel isolation. Consider the low current transfer ratio suitable for logic-level signaling rather than high-power switching. Verify thermal management needs within the specified operating temperature range.
Part of the ISP series offering surface-mount alternatives to traditional through-hole optocouplers. Designed for compact PCB layouts while maintaining standard isolation performance metrics found in legacy DIP packages.
MOC8108-SM is listed as a variant. Cross-reference with other manufacturers' phototransistor optocouplers ensuring identical pinout and isolation ratings.
