MOC217R2VM

Transistor, Photovoltaic Output Optoisolators Overview

The MOC217R2VM is a single-channel transistor output optocoupler manufactured by onsemi (formerly Fairchild Semiconductor). It features an infrared LED coupled to an NPN phototransistor with a base terminal for enhanced 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 minimum DC current transfer ratio of 100% at 10mA forward current, a maximum collector-emitter saturation voltage of 400mV, and a maximum collector current of 150mA. The input forward voltage is typically 1.07V with a maximum continuous forward current of 60mA. Switching characteristics include typical rise and fall times of 3.2µs and 4.7µs, respectively. It is housed in an 8-SOIC package.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the manufacturer designation carefully, as this component was originally produced by Fairchild Semiconductor and is now under onsemi. Confirm the specific suffix 'R2VM' corresponds to the tape-and-reel packaging format if automated assembly is required. Ensure compliance with RoHS directives and check for any recent Product Change Notifications regarding pinout or material composition updates from the current manufacturer.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a balance of moderate speed and high current gain is required for isolated switching applications. The presence of a base terminal allows for external biasing to optimize turn-off time, making it suitable for applications where standard phototransistors may exhibit excessive storage time. Compare against the MOCD217R2VM for dual-channel requirements or the FODM217CR2V for higher insulation ratings and different packaging constraints.

Transistor, Photovoltaic Output Optoisolators Part Context

The MOC217 series belongs to the family of small outline surface mount phototransistor optocouplers designed for general-purpose isolation. This specific variant utilizes an 8-lead SOIC package, offering a compact footprint for PCB layout efficiency while maintaining the electrical characteristics of the broader MOC217 line. It serves as a direct replacement for legacy through-hole equivalents in modern surface-mount designs.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

The MOCD217R2VM is a confirmed substitute part number from onsemi. Verify pin compatibility and package dimensions before substitution. Other variants such as MOC217R2M may differ in packaging or specific electrical tolerances.
