MOC8050XSM

Transistor, Photovoltaic Output Optoisolators Overview

The MOC8050XSM is a surface-mount photodarlington optocoupler manufactured by Isocom Components. It integrates a gallium arsenide infrared emitting diode with a monolithic silicon photodarlington detector, featuring a single channel and six pins in a plastic package. Key electrical parameters include a minimum collector-emitter breakdown voltage of 80V, a maximum forward current of 50mA, and a typical nominal current transfer ratio of 300%. The device offers a high isolation voltage of 5300Vrms and operates within a temperature range of -25°C to 100°C.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• Eliminated base connection on the photodarlington output to enhance noise immunity in high EMI environments
• High sensitivity to low input drive currents for efficient signal coupling
• Darlington output configuration providing high gain and collector-emitter breakdown voltage

Transistor, Photovoltaic Output Optoisolators Applications

• Interfacing and coupling systems of different potentials and impedance
• Solid state relays
• I/O interfaces for computers and programmable controllers
• Appliances and measuring instruments susceptible to high EMI levels

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'XSM' against official Isocom documentation to confirm exact packaging and tape-and-reel specifications. Ensure compliance requirements such as UL recognition or VDE testing are explicitly stated if required for your design. Cross-reference the datasheet revision date to confirm parameter stability before finalizing procurement.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when high noise immunity is critical due to the absence of a base lead on the photodarlington. It is suitable for applications requiring high sensitivity to low input currents and robust isolation between control and load circuits. Consider the surface-mount form factor for automated assembly processes.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the MOC8050 family of non-base-lead optically coupled isolators. It is designed as a replacement for legacy through-hole versions in modern surface-mount assemblies. The series is recognized for its ability to operate reliably in industrial environments with significant electromagnetic interference.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct pin-compatible replacements include the MOC8050M from Fairchild Semiconductor and standard MOC8050 variants from other manufacturers. Verify that substitute parts maintain the same 6-pin SMD footprint and Darlington output characteristics.
