MOC8204M

Transistor, Photovoltaic Output Optoisolators Overview

The MOC8204M is a single-channel transistor output optocoupler manufactured by onsemi. It integrates an aluminum gallium arsenide infrared emitting diode coupled to a high-voltage NPN silicon phototransistor with a base lead for switching speed control. The device provides electrical isolation with an insulation voltage of 4170 Vrms. Key electrical parameters include a maximum collector-emitter voltage of 400 V, a maximum collector current of 100 mA, and a minimum current transfer ratio of 20%. It operates within a temperature range of -40°C to +100°C and is housed in a PDIP-6 package.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• Integrates an infrared LED with a high-voltage NPN phototransistor for signal transmission

• Features a dedicated base lead on the phototransistor to optimize switching performance

Transistor, Photovoltaic Output Optoisolators Applications

• Industrial control systems requiring galvanic isolation
• Solid-state relay driver circuits
• Communication interface isolation

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify component authenticity through authorized onsemi distributors or certified partners. Confirm that the received parts match the specified PDIP-6 package and marking codes. Ensure compliance with RoHS directives as indicated in official documentation. Request relevant quality certificates and material declarations prior to final acceptance to guarantee supply chain integrity and product reliability.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when high-voltage isolation up to 400 V is required alongside standard transistor output characteristics. The inclusion of a base lead allows for improved switching speed compared to devices without this feature. Consider the PDIP-6 through-hole format for PCB layouts supporting manual or wave soldering processes. Evaluate thermal dissipation requirements against the 420 mW power dissipation limit during operation.

Transistor, Photovoltaic Output Optoisolators Part Context

The MOC8204M belongs to the MOC8204M series of transistor output optocouplers from onsemi. It shares functional similarities with other models such as the 4N38M, H11D1M, and H11D3M, which also utilize an infrared LED coupled to a phototransistor. These components are designed for general-purpose isolation applications where reliable signal transfer across potential barriers is necessary.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Publicly confirmed substitute part numbers include 4N38M, H11D1M, and H11D3M. Verify pinout compatibility and parameter equivalence before substitution.
