Triac-output optoisolator for AC load switching
The VO3063-X006 is a single-channel optoisolator with a triac output from Vishay, packaged in a 6-DIP through-hole package (0.400" lead spacing). It provides 5300Vrms isolation between the LED input and the triac output, with a 600 V off-state voltage rating that suits direct switching of 120 VAC or 240 VAC resistive and inductive loads. The zero-crossing circuit turns on the triac near the AC zero-voltage point, reducing inrush current and EMI in heater, lamp, and motor-start applications. The part carries cUR and UR agency approvals, confirming its acceptance for North American safety-listed equipment.
dV/dt immunity and false-trigger margin
A minimum static dV/dt of 1.5 kV/µs means the triac will not falsely trigger from fast voltage transients on the AC line — a common failure mode when switching inductive loads like contactors, solenoids, or small motors. If your application sees repetitive snubber-less switching, this rating gives you a clean margin over the 200–500 V/µs transients typical in industrial 240 VAC environments. The 200 µA typical holding current keeps the triac latched once triggered, even with low-load currents down to a few milliamps.
LED drive and on-state current budget
The LED requires a maximum trigger current of 5 mA to turn on the triac, with a typical forward voltage of 1.2 V. Maximum continuous LED forward current is 60 mA. The triac itself is rated for 100 mA RMS on-state current, which covers low-power loads such as solid-state relays driving small valves, indicator lamps, or logic-level AC inputs. For loads above 100 mA, the VO3063-X006 should drive an external power triac or SSR.
Temperature range and operating environment
The 100°C ceiling is the junction limit — derate the on-state current above 70°C per the datasheet thermal derating curve. Storage temperature exceeds the operating range, so the part can survive handling in unheated warehouses.
Lifecycle and compliance
It is ROHS3 compliant.
