Toshiba TLP531/TLP532 Photocoupler Datasheet
The TLP531 and TLP532 optocouplers combine a gallium‑arsenide infrared emitting diode with a photo‑transistor in a six‑lead DIP package. They are intended for general electronics applications such as computers, office equipment, measuring devices, industrial robotics, and domestic appliances.
Key specifications include a collector‑emitter voltage of 55 V, isolation voltage of 2500 Vrms, forward current up to 70 mA, and power dissipation up to 150 mW. The devices operate from –55 °C to 100 °C and include recommended operating conditions and switching characteristics. The document also outlines restrictions on use in safety‑critical or high‑reliability equipment.
