Photo Triac Optocoupler HENGTUO HT-3081-S1TA1 for Interface of Logic Systems and Industrial Controls
Product Description
The HT-304X_306X_308X series of devices each consist of a GaAs infrared emitting diode optically coupled to a monolithic silicon zero voltage crossing photo triac. They are designed for use with a discrete power triac in the interface of logic systems, such as solid-state relays, industrial controls, motors, solenoids, and consumer appliances. Key advantages include high input-output isolation voltage (Viso = 5,000Vrms), high repetitive peak off-state voltage (VDRM), and a high critical rate of rise of off-state voltage (dv/dt). Applicable in solenoid/valve controls, static power switches, AC motor drivers, and temperature control.
