The output is a Triac rated for 600 V off-state voltage and a maximum on-state RMS current of 70 mA, making it suitable for 120 VAC and 240 VAC line-voltage switching in industrial and appliance control boards. The zero-crossing feature minimizes inrush current and conducted EMI when the load is switched on near the AC line zero voltage. ## 3750 Vrms isolation and transient immunity With 3750 Vrms isolation between input and output, this coupler provides reinforced insulation for safety-rated designs where the control side must be galvanically separated from the mains-powered load. The minimum static dV/dt of 200 V/µs on the output ensures the triac does not falsely trigger on fast voltage transients from inductive load switching or line noise — a common failure point in noisy industrial environments. ## Trigger current and drive requirements The LED trigger current (Ift) is 10 mA maximum, with a typical forward voltage of 1.27 V. This means a standard 5 V or 3.3 V logic output can drive the input side through a current-limiting resistor without needing a separate driver transistor. The 30 µs turn-on time is fast enough for line-frequency (50/60 Hz) switching but not intended for high-speed PWM or phase-angle control. Once triggered, the triac latches on until the load current drops below the 600 µA typical hold current, which occurs naturally at the AC zero crossing. ## Package and temperature range Housed in a 6-pin SOP (6-SOP) package with 4.40 mm body width, the device is surface-mount and suited for automated assembly.","metaTitle":"Toshiba TLP266J(V4T7TL,E Triac Coupler, 600 V Off-State","metaDescription":"Toshiba TLP266J(V4T7TL,E single-channel triac output optocoupler with zero-crossing, 600 V off-state, 3750 Vrms isolation, 30 µs turn-on.
