    Products Detail

    The PC3ST21NSZ Series is a Phototriac Coupler that includes an infrared emitting diode (IRED) optically coupled to an output Phototriac. It features full wave control and is ideal for isolated driving of medium to high current Triacs. The DIP package provides 5.0kV isolation from input to output with superior commutative noise immunity. Key features include high repetitive peak off-state voltage (600V), zero crossing functionality, available I ranks, 4-pin DIP package, superior noise immunity (dV/dt: MIN. 1,000V/µs), lead-free options, double transfer mold construction for flow soldering, and high isolation voltage (5.0kV RMS).

    Key Features

    • High repetitive peak off-state voltage (V_DRM: 600V), Zero crossing functionality (V_OX: MAX. 20V), I ranks available, 4 pin DIP package, Superior noise immunity (dV/dt: MIN. 1,000V/µs), Lead-free components available, Double transfer mold construction (Ideal for Flow Soldering), High isolation voltage between input and output (V_iso (rms): 5.0kV)

    Application scenarios

    • Triggering for Triacs used to switch on and off devices which require AC Loads. For example heaters
    • fans
    • motors
    • solenoids
    • and valves. AC line control in power supply applications.
