MOC206M

Transistor, Photovoltaic Output Optoisolators Overview

The MOC206M is a single-channel optocoupler featuring a phototransistor output with an integrated base terminal. It utilizes a gallium arsenide infrared emitting diode optically coupled to a monolithic phototransistor. The device provides 2500Vrms isolation voltage and operates within a temperature range of -40°C to 100°C. Key electrical parameters include a maximum collector-emitter saturation voltage of 400mV, a DC forward current of 60mA, and a typical current transfer ratio of 63% at 10mA input. It is housed in an 8-SOIC package.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'M' to ensure the correct tape-and-reel or tube packaging variant is selected, as suffixes may indicate different packing quantities or handling specifications. Confirm that the 8-SOIC footprint matches the target PCB design. Ensure the component meets RoHS compliance requirements for the intended market. Cross-reference the datasheet revision date to confirm parameter stability before finalizing the bill of materials.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when base-driven phototransistor outputs are required for improved saturation characteristics and switching speed. Compare the 400mV Vce(sat) against alternatives if low voltage drop is critical. Consider the 2500Vrms isolation rating relative to system safety standards. Evaluate the -40°C to 100°C operating range against environmental conditions. Verify compatibility with the driving circuit's current limits given the 60mA maximum forward current specification.

Transistor, Photovoltaic Output Optoisolators Part Context

The MOC206M belongs to the MOC205/206/207/208 series of single-channel optocouplers from onsemi. This family offers transistor output options with varying current transfer ratios and switching speeds. The MOC206M specifically balances moderate speed with reliable saturation performance. It serves as a legacy alternative to newer high-speed digital isolators where galvanic isolation via optical means is preferred.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

The MOC206VM is listed as a discontinued part with the MOC206M identified as a parameter-equivalent replacement. Verify pinout compatibility and exact CTR specifications when substituting. Other potential equivalents should be evaluated based on isolation voltage and package dimensions.
