MOC205M

Transistor, Photovoltaic Output Optoisolators Overview

The MOC205M is a single-channel transistor output optocoupler manufactured by onsemi. It integrates a gallium arsenide infrared emitting diode with a monolithic silicon phototransistor detector. The device is housed in an 8-pin SOIC-Narrow package, designed for surface mount applications. Key electrical specifications include a maximum collector-emitter voltage of 30 V and a peak forward current rating of 60 mA. The unit provides an isolation voltage of 2500 VRMS. Typical performance metrics feature a minimum current transfer ratio of 40% and a maximum of 80%. Switching characteristics specify a rise time of 3.2 µs and a fall time of 4.7 µs.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required packaging formats and tape-and-reel quantities. Confirm that the selected variant meets the necessary insulation standards for the target application environment. Cross-reference the manufacturer datasheet revision to validate the electrical parameters against the most recent product specifications before finalizing component selection.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a single-channel isolation interface is required for low-to-medium speed digital signals. The NPN phototransistor output configuration suits applications requiring standard sinking or sourcing loads. Evaluate the thermal dissipation capabilities of the SOIC package relative to the expected ambient operating conditions. Ensure the forward current requirements remain within the specified 60 mA limit to maintain optimal lifetime and reliability.

Transistor, Photovoltaic Output Optoisolators Part Context

This device belongs to the MOC205 series of single-channel optocouplers produced by onsemi. The series utilizes a standard phototransistor output architecture common in general-purpose isolation applications. The MOC205M specifically denotes the version packaged in an 8-lead small outline integrated circuit (SOIC) format, distinguishing it from through-hole or wider surface-mount variants within the same functional family.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct substitutes may include other single-channel transistor output optocouplers with compatible pinouts and similar electrical ratings. Verify that alternative components meet the same 2500 VRMS isolation requirement and fit within the 8-pin SOIC-Narrow footprint constraints.
