MOC8204W

Transistor, Photovoltaic Output Optoisolators Overview

The MOC8204W is a single-channel transistor output optocoupler manufactured by onsemi. It features an NPN phototransistor output and provides galvanic isolation with a rated insulation voltage of 5300 Vrms. The device supports a maximum collector-emitter voltage of 400 V and a continuous collector current of 100 mA. It operates within a temperature range of -40°C to +100°C and is housed in a 6-pin DIP package.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• Provides high-voltage galvanic isolation for signal transmission between circuits
• Features an NPN phototransistor output for switching applications
• Supports wide operating temperature ranges for industrial environments

Transistor, Photovoltaic Output Optoisolators Applications

• High-voltage power supply feedback loops
• Industrial control system isolation
• Solid-state relay driver circuits

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'W' against official datasheets to confirm the 5300 Vrms insulation rating, as other variants like MOC8204M specify 4170 Vrms. Ensure the package type matches the required PCB footprint. Confirm RoHS compliance status through the manufacturer's documentation before finalizing procurement specifications.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when circuit requirements demand isolation voltages exceeding standard 5000 Vrms ratings. Compare the 400 V collector-emitter voltage limit against peak transient voltages in the load circuit. Evaluate the 100 mA collector current capability against the driven load requirements to ensure adequate margin for reliable switching operation.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the MOC8204 series of transistor output optocouplers from onsemi. The series includes variants such as MOC8204M and MOC8204SM, which share similar electrical characteristics but differ in packaging and specific insulation voltage ratings. The MOC8204W variant is distinguished by its higher insulation voltage specification.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct substitutes include MOC8204M and MOC8204SM, provided the lower 4170 Vrms insulation rating is acceptable for the application. Verify pinout compatibility and thermal performance differences between the DIP-6 and SMD packages if transitioning form factors.
