That gives you nearly 2.4× headroom above the 340 V peak of a 240 VAC sine wave, so transient spikes from inductive loads or line switching won't punch through the output triac. The non-zero-crossing output means the internal LED can trigger the triac at any point in the AC cycle — essential for phase-angle dimming, soft-start motor control, or any application where you need to fire the load partway through a half-cycle. If your design only needs on/off at the zero crossing, a zero-crossing optotriac like the MOC3063M would simplify the drive. ## Noise immunity and trigger current — bench-fit checks A minimum static dV/dt of 1 kV/µs means the output triac won't falsely commutate on fast voltage edges from nearby relays, motor drives, or switching power supplies. In a panel with a VFD running at 4–8 kHz carrier frequency, that margin keeps the load from turning on when you didn't command it. The LED trigger current (Ift) is 10 mA max, and the typical hold current (Ih) is 540 µA. A 5 V logic output driving a 330 Ω series resistor delivers about 12 mA — enough to saturate the LED over temperature. The 60 mA absolute max DC forward current gives you room to drive it harder if the LED degrades over life, but staying near 10–15 mA keeps the thermal stress low. ## Active production — no LTB pressure ROHS3 compliant and UL recognized. The through-hole DIP-6 package is a standard footprint that mates with common DIP sockets or solders directly into plated through-holes — no reflow profile to worry about. ## Sourcing and ordering this part We source it to order against your BOM quantity — confirm the lead time and current pricing by submitting an RFQ.

The output triac fires as soon as the LED current exceeds the trigger threshold, regardless of the AC line voltage. Use it for phase-angle control (dimming, soft-start) where you need to switch at any point in the cycle. For simple on/off at voltage zero, choose a zero-crossing variant like the MOC3063M."},{"question":"What is the closest functional second-source to the MOC3072M?","answer":"The MOC3073M is a near-parametric match: same 1 kV/µs dV/dt, same 4170 Vrms isolation, same through-hole DIP-6 package, same non-zero-crossing output, and the same -40°C to 85°C temperature range. The only difference is the switching current rating — the MOC3072M is rated for 0.006 A, while the MOC3073M is rated for 0.01 A. For most low-current triac drive applications (gate drive of an external power triac), either works. Confirm the load current in your design before swapping."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/onsemi/MOC3072M","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/onsemi/MOC3072M when reusing this data.
