The TLP521, TLP521‑2 and TLP521‑4 are optically coupled isolators that combine an infrared LED with an NPN silicon phototransistor in a compact dual‑in‑line package. They are offered in standard, G (lead‑spread), and surface‑mount (SM) versions and are suitable for computer terminals, industrial system controllers, and measuring instruments.
The datasheet lists detailed electrical parameters such as forward voltage, reverse current, breakdown voltages, isolation voltage, current transfer ratio, and power dissipation, together with absolute maximum ratings and temperature limits. Graphs illustrate collector‑power dissipation versus ambient temperature and current transfer ratio versus forward current.
