Toshiba TLP124 Photocoupler Datasheet
The TLP124 is a miniature GaAs infrared emitting diode coupled to a photo‑transistor, intended for surface‑mount assembly in office machines, programmable controllers, and telecom equipment. It offers a high isolation voltage and a current transfer ratio of at least 100%.
The sheet lists key specifications such as collector‑emitter voltage (80 V min), isolation voltage (3750 Vrms min), forward current (50 mA), power dissipation (150 mW), and recommended operating temperature range (‑25 °C to 75 °C). It also includes pin‑out details, switching times, and safety restrictions for proper use.
