MOC211VM

Transistor, Photovoltaic Output Optoisolators Overview

The MOC211VM is a single-channel phototransistor output optocoupler manufactured by onsemi, formerly Fairchild Semiconductor. It features an infrared emitting diode coupled to a phototransistor with a base terminal for improved switching performance. 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 voltage of 30V, a DC forward current limit of 60mA, and a minimum current transfer ratio of 20% at 10mA input. Typical switching times are 7.5µs (turn-on) and 5.7µs (turn-off). It is housed in an 8-SOIC surface-mount package.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for recent Product Change Notifications (PCN) regarding assembly or material declarations. Ensure the specific suffix matches required packaging and regulatory standards before finalizing procurement orders.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when fast switching speeds are required compared to standard phototransistor optocouplers. The base terminal allows for external biasing to further optimize turn-off times. Ensure the application voltage does not exceed the 30V collector-emitter rating and that isolation requirements are met by the 2500Vrms specification.

Transistor, Photovoltaic Output Optoisolators Part Context

The MOC211VM belongs to the MOC21x series of small outline optocouplers originally developed by Fairchild Semiconductor. This series is designed for general-purpose isolation tasks where compact size and reliable performance are critical. The VM suffix typically denotes VDE approval and specific packaging configurations within the product line.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct replacements may include MOC211M or MOC211VM from onsemi. Verify pinout compatibility and electrical specifications against the original design requirements before substitution.
