PC3ST21NIZB Datasheet

PC3ST21NIZB DIP 4pin Phototriac Coupler

PC3ST21NSZ Series Phototriac Coupler include an infrared emitting diode (IRED) optically coupled to an output Phototriac. These devices feature full wave control and are ideal isolated drivers for medium to high current Triacs. DIP package provides 5.0kV isolation from input to output with superior .

Features

1. High repetitive peak off-state voltage (VDRM : 600V) 2. Zero crossing functionality (VOX : MAX. 20V) 3. IFT ranks available (see Model Line-up section in this datasheet) 4. 4 pin DIP package 5. Superior noise immunity (dV/dt : MIN. 1 000V/µs) 6. Lead-free components are also available (see Model Line-up section in this datasheet) 7. Double transfer mold construction (Ideal for Flow Soldering) 8. High isolation voltage between input and output (Viso(rms) : 5.0kV)
■ Applications 1. Triggering for Triacs used to switch on and off devices which require AC Loads. For example heaters, fans, moto.
