MOC205VM

Transistor, Photovoltaic Output Optoisolators Overview

The MOC205VM is a single-channel phototransistor output optocoupler manufactured by onsemi. It features an NPN phototransistor with a base terminal for improved switching performance and stability. The device provides electrical isolation of 2500 Vrms between the input LED and output transistor. Key electrical parameters include a maximum collector-emitter voltage (Vceo) of 30 V, a maximum collector current (Ic) of 150 mA, and a forward voltage (Vf) of approximately 1.15 V at 60 mA forward current. The typical rise time is 3.2 µs and fall time is 4.7 µs. The component is housed in an 8-SOIC surface-mount package.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• Integrated base terminal on the phototransistor output to enhance switching speed and reduce storage time.

• Designed for surface-mount assembly using the compact 8-SOIC package format.

Transistor, Photovoltaic Output Optoisolators Applications

• Solid-state relay interfaces
• Microcontroller input/output isolation
• Signal transmission across isolated ground planes

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'VM' against the official datasheet to confirm the packaging type and material compliance status. Ensure the procurement source provides valid RoHS declarations and material disclosure documents consistent with onsemi standards. Cross-reference the manufacturer part number to avoid confusion with similar variants such as MOC205M or MOC205R2M which may differ in packaging or internal specifications.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a phototransistor output with a base pin is required for faster switching applications compared to standard base-less variants. The 8-SOIC package is suitable for automated surface-mount assembly processes. Verify that the circuit design accommodates the 30 V collector-emitter voltage rating and the 150 mA maximum collector current limits under all operating conditions.

Transistor, Photovoltaic Output Optoisolators Part Context

This component belongs to the MOC205 series of single-channel optocouplers from onsemi. The series includes various packages and suffixes, such as the through-hole MOC205M and the reel-packaged MOC205R2M. The MOC205VM specifically denotes the 8-SOIC surface-mount variant with tube packaging, maintaining the core phototransistor functionality within a compact footprint suitable for modern PCB designs.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct substitutes include MOC205M and MOC205R2M. Note that MOC205M typically uses a DIP-6 package, requiring mechanical adaptation. MOC205R2M shares the SOIC-8 package but may have different packaging quantities or minor parameter variations; verify datasheet compatibility before substitution.
