The TLP280 and TLP280-4 are thin, surface‑mount optocouplers designed for applications such as PCMCIA modems and programmable controllers. Each device contains a gallium‑arsenide infrared emitting diode optically coupled to a phototransistor, with the LED pins tied together and the detector pins tied together for two‑terminal operation.
Key electrical characteristics include a collector‑emitter voltage rating of 80 V (minimum), isolation voltage of 2500 V (minimum), forward current of 50 mA RMS, and typical forward voltage of about 1.15 V at 10 mA. Detailed tables provide individual and coupled characteristics, isolation resistance, and switching times for various operating conditions.
