MOC205R2M

Transistor, Photovoltaic Output Optoisolators Overview

The MOC205R2M is a single-channel phototransistor output optocoupler manufactured by onsemi, designed for surface-mount applications in an 8-SOIC package. It provides electrical isolation with a maximum insulation voltage of 2500Vrms. The device features an NPN phototransistor output with a base connection, supporting a maximum collector current of 150mA and a collector-emitter voltage of 30V. Key electrical parameters include a forward current of 60mA, a typical forward voltage of 1.15V, and a saturation voltage of 400mV. The current transfer ratio ranges from 40% to 80% at 10mA input. Switching characteristics specify rise and fall times of 3.2µs and 4.7µs, respectively, with operating temperatures spanning -40°C to 100°C.

• Provides robust electrical isolation between input and output circuits via a phototransistor interface.
• Integrates a base terminal on the phototransistor output to facilitate faster switching and improved linearity.
• Designed for surface-mount technology using a compact 8-SOIC package suitable for automated assembly.

Transistor, Photovoltaic Output Optoisolators Applications

• General-purpose signal isolation in industrial control systems
• Switching power supply feedback loops
• Microcontroller I/O isolation interfaces

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify component authenticity through authorized onsemi distributors or certified partners. Confirm RoHS compliance status and check for specific ordering suffixes that may indicate tape-and-reel packaging variations. Ensure the supplier provides valid traceability documentation and material declarations consistent with the manufacturer's official specifications.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when high-speed switching performance is required alongside standard isolation levels. The integrated base pin allows for external biasing to optimize response time compared to base-less variants. Ensure the application voltage does not exceed the 30V collector-emitter limit and verify thermal management capabilities within the specified temperature range.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the MOC205 family of single-channel optocouplers. It shares functional similarities with other devices in the series but is distinguished by its specific SOIC-8 surface-mount packaging and the inclusion of a phototransistor base terminal. It serves as a modern replacement for older through-hole equivalents in space-constrained designs.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct substitutes include the MOC205M and MOC205R2. Verify pinout compatibility and ensure the alternative part meets the same 2500Vrms isolation and 150mA output current requirements.
