The 800 V off-state rating means it can directly block the peak of a 240 VAC line with substantial margin, making it suitable for residential and light industrial AC load switching without an external snubber in many designs. A built-in zero-crossing circuit triggers the Triac only near the AC voltage zero, which minimizes inrush current and conducted EMI when switching resistive or lightly inductive loads such as heaters, solenoids, or incandescent lamps. ## 600 V/µs dV/dt immunity and drive current Minimum static dV/dt is 600 V/µs, which prevents false turn-on from fast voltage transients on the AC line — a common failure mode in motor-drive or relay-coil environments where back-EMF spikes appear across the Triac. Maximum LED trigger current (Ift) is 10 mA, with a typical forward voltage of 1.3 V. A standard 5 V or 3.3 V logic output can drive the LED through a current-limiting resistor; the 60 mA absolute maximum DC forward current leaves headroom for derating at elevated temperatures. Typical holding current (Ih) is 500 µA, which means the Triac will stay latched once triggered as long as the load current exceeds this threshold — important for low-power loads that might drop below holding current near the zero crossing. ## Active production, through-hole 6-DIP package The through-hole format simplifies manual prototyping and rework compared to surface-mount alternatives. Operating temperature range is -40°C to 85°C, covering most indoor and outdoor commercial/industrial environments. UL approved for safety-recognised designs.","metaTitle":"MOC3082M onsemi Optoisolator Triac Output 6-DIP Active","metaDescription":"onsemi MOC3082M Optoisolator, Triac output, 800V off-state, 4170Vrms isolation, zero-crossing, 600V/µs dV/dt.

The off-state voltage is rated at 800 V, which is the maximum repetitive peak voltage the Triac output can block when the LED is off. This is more than sufficient for 240 VAC line switching (peak ~340 V) and provides margin for transient overvoltages."},{"question":"What is the difference between MOC3082 and MOC3083?","answer":"The MOC3082 and MOC3083 are both zero-crossing Triac output optoisolators from onsemi. The primary difference is the LED trigger current (Ift) maximum: MOC3082 specifies 10 mA max, while the MOC3083 typically specifies a lower Ift of 5 mA max. For the MOC3082M, the 10 mA Ift is compatible with standard logic-level drive; the MOC3083 may be preferred for lower-power drive circuits. Confirm the exact datasheet for the MOC3083 before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/onsemi/MOC3082M","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/onsemi/MOC3082M when reusing this data.
