MOC216M

Transistor, Photovoltaic Output Optoisolators Overview

The MOC216M is a single-channel phototransistor output optocoupler manufactured by Fairchild Semiconductor, now part of onsemi. It features an NPN phototransistor with a base terminal for enhanced switching performance and isolation capabilities. The device provides 2500 Vrms insulation voltage between the input LED and output transistor. Key electrical parameters include a minimum current transfer ratio (CTR) of 50% at 1 mA forward current, a maximum collector-emitter saturation voltage of 400 mV, and a peak forward current rating of 60 mA. The typical rise time is 3.2 µs and fall time is 4.7 µs. It operates within a temperature range of -40°C to +100°C and is housed in an 8-SOIC surface-mount package.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• Integrates an NPN phototransistor with a dedicated base terminal to facilitate faster turn-off times and improved noise immunity compared to standard configurations.
• Provides robust galvanic isolation with a 2500 Vrms dielectric strength, ensuring safety compliance for low-voltage control interfacing with high-voltage circuits.
• Designed for surface-mount assembly in compact 8-SOIC packages, supporting automated manufacturing processes while maintaining reliable thermal dissipation.

Transistor, Photovoltaic Output Optoisolators Applications

• Solid-state relay driver circuits requiring fast switching speeds
• Interface modules connecting microcontrollers to AC or DC power loads
• Signal isolation in industrial automation control systems

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify component authenticity through authorized distributors, as the MOC216M series has been discontinued by Fairchild Semiconductor. Confirm that replacement units from onsemi meet original datasheet specifications. Check RoHS compliance status and ensure packaging matches required reel or cut-tape formats for production lines. Validate lot traceability for critical applications.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when specific base-terminal optimization for speed is required rather than generic phototransistor outputs. Compare CTR requirements against load conditions to ensure adequate drive capability. Ensure PCB layout accommodates the 8-SOIC footprint and maintains creepage distances consistent with the 2500 Vrms isolation rating for safety standards.

Transistor, Photovoltaic Output Optoisolators Part Context

The MOC216M belongs to the MOC21xM family of small-outline surface-mount optocouplers. This series includes variants like the MOC215M and MOC217M, differentiated primarily by their current transfer ratios. The MOC216M specifically targets applications needing moderate gain with enhanced switching characteristics due to its base pin configuration.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Public confirmed substitute part numbers are not explicitly listed in the provided documentation. As the product is marked obsolete, verify compatibility with direct replacements such as the MOC217M if higher CTR is acceptable, or consult manufacturer cross-reference guides for equivalent modern equivalents.
