MOC8204SM

Transistor, Photovoltaic Output Optoisolators Overview

The MOC8204SM is a single-channel transistor output optocoupler manufactured by onsemi. It features an NPN phototransistor output and operates in a surface-mount (SMD/SMT) 6-pin Gull Wing package. 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%. The device provides high isolation with an insulation voltage of 4170 Vrms. It supports a forward current of 80 mA with a forward voltage of 1.5 V. Power dissipation is rated at 420 mW, and it functions within a temperature range of -40°C to +100°C.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• High voltage isolation capability for safe signal transmission between isolated circuits

• Surface-mount packaging design suitable for automated assembly processes

Transistor, Photovoltaic Output Optoisolators Applications

• Industrial control systems requiring galvanic isolation
• Power supply feedback loops for voltage regulation
• Solid-state relay driver circuits
• Microcontroller interface isolation for noise immunity

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'SM' confirms the surface-mount gull-wing package variant distinct from through-hole versions. Confirm RoHS compliance status via official documentation before integration. Ensure storage conditions maintain component integrity. Validate that the 4170 Vrms isolation rating meets system safety requirements. Check for any recent datasheet revisions affecting mechanical dimensions or electrical limits.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Choose this component when high voltage isolation and compact surface-mount form factor are required. The 400 V collector-emitter voltage supports high-side switching applications. Consider the 20% minimum current transfer ratio for logic-level interfacing needs. Evaluate thermal management capabilities given the 420 mW power dissipation limit. Compare against other channel counts if multiple isolation paths are necessary.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the MOC8204M series of transistor output optocouplers. It shares core electrical characteristics with the through-hole MOC8204M variant but differs in mounting style. The series is designed for general-purpose isolation tasks in industrial and consumer electronics. It complements onsemi's broader portfolio of signal conditioning and interface components.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

The MOC8204M is a direct functional equivalent with identical electrical specifications but utilizes a through-hole PDIP-6 package instead of surface-mount. Verify footprint compatibility during substitution. No other cross-model substitutes are confirmed in public documentation.
