■ Description

S2S4 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.

SOP package provides 3.75kV 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. 35V)

3. IFT ranks available (see Model Line-up section in this datasheet)

4. 4 pin Mini-flat package

5. Superior noise immunity (dV/dt : MIN. 100V/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) : 3.75kV)

■ 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.
