MOC212M

Transistor, Photovoltaic Output Optoisolators Overview

The MOC212M is a single-channel optocoupler manufactured by Fairchild Semiconductor, featuring a GaAs infrared LED coupled to a phototransistor with base output. It provides electrical isolation via a 2500Vrms insulation rating. The device operates with DC input and supports an output voltage of up to 30V and a continuous output current of 150mA per channel. Typical rise and fall times are specified at 3.2µs and 4.7µs respectively. It is housed in an 8-SOIC package.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• Single-channel configuration integrating an infrared LED emitter with a phototransistor receiver for signal transmission across isolated circuits.
• Phototransistor output includes a dedicated base terminal, allowing for external biasing or speed adjustment capabilities.
• Provides high-voltage isolation between input and output sides to protect sensitive control circuitry from noise and potential differences.

Transistor, Photovoltaic Output Optoisolators Applications

• Signal isolation in industrial control systems
• Interface between microprocessors and power switching devices
• Noise immunity enhancement in data communication lines

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific manufacturer source, as the component was originally produced by Fairchild Semiconductor and later integrated into onsemi's portfolio. Confirm the datasheet revision and ensure the part status aligns with project requirements, noting that some sources indicate this series may be obsolete or discontinued depending on the specific manufacturing lot and region.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a single-channel transistor output optocoupler with a base pin is required for moderate-speed applications. Ensure the design accommodates the 30V output voltage limit and 150mA current capacity. Verify compatibility with the 8-SOIC footprint during PCB layout. Consider the typical switching speeds if timing constraints are critical for the application.

Transistor, Photovoltaic Output Optoisolators Part Context

The MOC212M belongs to the family of small outline optocouplers designed for general-purpose isolation tasks. It shares architectural similarities with related models like the MOC211M and MOC213M, differing primarily in internal gain characteristics. These components are widely recognized for their reliability in isolating low-power logic signals from higher-power loads.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Check for equivalents within the same product family, such as the MOC211M or MOC213M, which share the SOIC-8 package and basic functionality. Verify pinout compatibility and electrical specifications before substitution. Note that availability may vary due to the component's potentially obsolete status.
