This datasheet provides detailed information on TLP127's specifications, including application areas, package types, absolute maximum ratings, pin configuration, storage temperature range, operating temperature range, lead soldering temperature, and total package.
The TLP127 is a miniature surface‑mount optocoupler that combines a gallium‑arsenide infrared emitting diode with a Darlington phototransistor and an integral base‑emitter resistor. It provides up to 300 V collector‑emitter voltage and a minimum current transfer ratio of 1000 %.
The document lists absolute maximum ratings, electrical characteristics, switching performance, and recommended operating conditions such as a supply voltage up to 200 V, forward current up to 50 mA, and operating temperature from –55 °C to 85 °C. It also includes restrictions on product use and safety warnings for the GaAs material.
