PC3ST21NSZB

PC3ST21NSZ Series ∗Non-zero cross type is also available. (PC3ST11NSZ Series) PC3ST21NSZ Series VDRM : 600V, Zero cross type DIP 4pin Phototriac Coupler for triggering ■ 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. DIP package provides 5.0kV isolation from input to output with superior commutative noise immunity. ■ Agency approvals/Compliance 1. Recognized by UL1577 (Double protection isolation), file No. E64380 (as model No. 3ST21) 2. Approved by CSA, file No. CA95323 (as model No. 3ST21) 3. Package resin : UL flammability grade (94V-0) ∗ DIN EN60747-5-2 (successor standard of DIN VDE0884) approved type is also available. (PC3SH21YFZ Series) ■ 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, motors, solenoids, and valves. 2. AC line c...
