Triac output with zero-crossing for inductive load switching
The zero-crossing function gates the Triac on only near the AC voltage zero, reducing inrush current and EMI when switching inductive loads like solenoids, relays, or small motors. Rated for 600 V off-state voltage and 100 mA RMS on-state current, the VO3062 suits line-voltage AC control circuits up to 240 VAC nominal with adequate margin. The 5300 Vrms isolation barrier separates the low-voltage logic side from the high-voltage load side, meeting reinforced insulation requirements per IEC 60950-1 for equipment with 250 V working voltage.
Isolation, dV/dt, and noise immunity in industrial environments
A minimum static dV/dt of 1.5 kV/µs on the Triac output prevents false triggering from fast voltage transients on the AC line — a common failure mode in motor-drive or contactor-heavy panels where switching noise couples through parasitic capacitance. This rating ensures the output remains off when the LED is not driven, even under noisy line conditions. The 200 µA typical hold current (Ih) keeps the Triac latched once triggered, with a 10 mA maximum LED trigger current (Ift) to guarantee turn-on across temperature and LED degradation. Operating temperature spans -55°C to 100°C, covering industrial and telecom enclosure environments without derating. The 6-DIP package with 7.62 mm pin pitch fits standard DIP sockets or through-hole PCB layouts, with the 0.300" body width allowing 0.100" row spacing for manual or wave-solder assembly.
