Toshiba TLP521-1/2/4 Optocoupler Datasheet
The TLP521‑1, TLP521‑2 and TLP521‑4 are solid‑state optocouplers that combine a gallium‑arsenide infrared emitting diode with a photo‑transistor. They are offered in 8‑lead (2‑channel) and 16‑lead (4‑channel) DIP packages for use in general electronics, industrial robotics, and appliance applications.
Key specifications include a 2500 Vrms isolation voltage, 55 V collector‑emitter voltage, forward current up to 70 mA, and operating temperature from –55 °C to 100 °C. The datasheet also provides recommended supply voltages (5‑24 V), switching times, and characteristic curves for various duty cycles.
