■ Description
PC3SF21YVZ Series reinforced insulation type 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 commutative noise immunity.

■ 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. 6 pin DIP package
5. Reinforced insulation type (MIN. 0.4mm internal separation)
6. Superior noise immunity (dV/dt : MIN. 1 000V/µs)
7. Lead-free components are also available (see Model Line-up section in this datasheet)
8. Double transfer mold construction (Ideal for Flow Soldering)
9. 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, motors, solenoids, and valves.
2. AC line control in power supply applications.
