MOC212M

Transistor, Photovoltaic Output Optoisolators Overview

The MOC212M is a single-channel transistor output optocoupler manufactured by onsemi. It integrates a gallium arsenide infrared emitting diode with a monolithic silicon phototransistor detector in an 8-pin SOIC-Narrow package. Key electrical specifications include a maximum collector-emitter voltage of 30 V, a peak forward current of 60 mA, and an isolation voltage of 2500 Vrms. The device operates within a temperature range of -40°C to +100°C and features a typical current transfer ratio of 50% at 10 mA input.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix (e.g., R2M) against the datasheet to confirm packaging type such as reel or tube. Ensure compliance with RoHS directives if required by the target application. Confirm that the 8-pin SOIC footprint matches the PCB design constraints before finalizing procurement orders.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when single-channel isolation with a phototransistor output is required. Consider the 30 V collector-emitter voltage limit for low-voltage logic interfacing. Evaluate the 2500 Vrms isolation rating against the system's safety requirements. Compare propagation delays if high-speed switching is necessary.

Transistor, Photovoltaic Output Optoisolators Part Context

This device belongs to the MOC212M series of transistor output optocouplers from onsemi. It is part of a broader family of optoelectronic components designed for signal isolation. The series typically offers various packaging options and insulation ratings to suit different industrial and consumer electronics applications.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Check for direct pin-compatible substitutes within the same manufacturer's portfolio. Verify that alternative parts meet the 30 V collector-emitter voltage and 2500 Vrms isolation requirements. Ensure the replacement maintains the NPN phototransistor output configuration for circuit compatibility.
