    Products Detail

    The PC3ST21NSZ Series is a Phototriac Coupler designed for triggering Triacs in AC load switching applications. It features an infrared emitting diode (IRED) optically coupled to a phototriac output, providing full wave control. The device offers high repetitive peak off-state voltage (600V), zero-crossing functionality, and superior noise immunity (dV/dt: MIN. 1000V/µs). It comes in a 4-pin DIP package with 5.0kV isolation between input and output. The series includes both zero-crossing and non-zero-crossing types, with lead-free options available. Double transfer mold construction makes it suitable for flow soldering.

    Key Features

    • High repetitive peak off-state voltage (V_DRM: 600V), Zero crossing functionality (V_OX: MAX. 20V), I ranks available (Rank B and C), 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 (V_iso: 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.
