PC3ST21NIZBF - DIP 4pin Phototriac Coupler

Download the PC3ST21NIZBF datasheet PDF. This datasheet also covers the PC3ST21NSZ variant, as both devices belong to the same dip 4pin phototriac coupler family and are provided as variant models within a single manufacturer datasheet.

General Description

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.

Key Features

  • 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).
