TLP281,TLP281-4 is a very small and thin coupler,suitable for surface mount assembly in applications such as PCMCIA Fax modem,programmable controllers.
The TLP281 and TLP281-4 are miniature GaAs optocouplers designed for surface‑mount applications such as PCMCIA fax modems and programmable controllers. They consist of an infrared emitting diode optically coupled to a photo‑transistor and are supplied in 4‑pin and 16‑pin packages.
Key specifications include a collector‑emitter voltage rating of 80 V, forward current up to 50 mA, isolation voltage of 2500 Vrms, and operation over a temperature range of –55 °C to 100 °C. The document also provides pin assignments, switching times, and safety restrictions for use in electronic equipment.
