K3020P/K3020PG Series Optocouplers with LED Input and Phototriac Output.
The K3020P/K3020PG series optocouplers are phototransistor devices with a gallium arsenide infrared LED, offered in a 6‑lead DIP package. They feature extra‑low coupling capacitance (≈0.2 pF), high common‑mode rejection, and meet UL 94‑VO isolation standards. The series is intended for safety isolation in monitors, air conditioners, line switches, solid‑state relays, and microwave applications.
The document lists absolute maximum ratings, electrical characteristics, and typical performance curves, as well as mechanical dimensions and compliance information (RoHS, lead‑free, UL1577, IEC standards). It also includes safety policy statements and legal disclaimer notices.
