MOC8102XSM

Transistor, Photovoltaic Output Optoisolators Overview

The MOC8102XSM is a surface-mount optically coupled isolator manufactured by Isocom Components. It integrates an infrared LED and an NPN silicon phototransistor within a compact package. The device features a high isolation voltage of 5.3kVRMS and 7.5kVPK, ensuring robust signal transmission between systems with different potentials. A key design characteristic is the unconnected base pin, which significantly improves noise immunity in high EMI environments. This component is engineered for reliable performance in industrial control applications requiring precise electrical isolation.

Transistor, Photovoltaic Output Optoisolators Applications

• DC motor controllers
• Industrial system controllers
• Signal transmission between systems of different potentials and impedances

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify that the suffix 'XSM' corresponds to the specific surface mount tape and reel packaging variant as defined by Isocom Components documentation. Confirm lead spread options if through-hole compatibility is required, noting that standard DIP variants may differ physically. Ensure the procurement order explicitly references the full part number to distinguish from other MOC8102 series configurations.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when surface mount technology is required for optocouplers with high noise immunity needs. The unconnected base pin makes it suitable for environments with significant electromagnetic interference. Compare CTR specifications against circuit requirements, as values vary across the MOC8102 series. Ensure the 5.3kVRMS isolation rating meets the safety standards of the target application.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the MOC8101-8105 series of non-base lead optically coupled isolators. These devices are designed as replacements for legacy components like the CNY17F2. The series is characterized by its NPN phototransistor output and plastic dual in-line construction, adapted here for surface mount integration.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct substitutes include the MOC8102W or CNY17F2W in DIP packages, though physical mounting differences exist. Surface mount equivalents such as the SFH628A-4SMT&R offer similar isolation but differ in input/output characteristics. Verify pinout compatibility before substitution.
