The 10 kV/µs minimum static dV/dt keeps the output from false-firing on fast voltage edges from motor drives, contactor coils, or switched inductive loads. With no zero-crossing circuit, the triac fires immediately when the LED current exceeds the 1.3 mA max trigger threshold. This suits phase-angle control, resistive heater modulation, and any application where turn-on timing relative to the AC waveform matters. ## Parametric deep-dive: drive current and hold current The LED forward voltage is 1.28 V typical at 30 mA max DC forward current. The 500 µA hold current means the triac latches once triggered and stays on until the load current drops below that level — typical for AC loads where the current crosses zero naturally each half-cycle. Turn-on time is 60 µs, fast enough for most line-frequency switching but not for high-frequency PWM. The 5000 Vrms isolation with cUL, FIMKO, and UL approvals supports reinforced insulation requirements in industrial and appliance power supplies. ## Lifecycle and sourcing position in a 6-SMD Gull Wing package for surface-mount assembly. Sourced per RFQ against your BOM quantity.","metaTitle":"FOD4216S onsemi Optoisolator Triac Output 5000Vrms 600V Bulk","metaDescription":"onsemi FOD4216S optoisolator with Triac output, 5000Vrms isolation, 600V off-state, 10kV/µs dV/dt.
