Toshiba TLP250 Optocoupler Datasheet
The TLP250 is a GaAs light‑emitting diode and integrated photodetector optocoupler in an 8‑lead DIP package, intended for gate‑driving circuits of IGBT or power MOSFET devices. The document describes its construction, pin configuration, and recommended application notes such as a 0.1 µF bypass capacitor between pins 8 and 5.
Key electrical ratings are listed, including absolute maximum ratings, recommended operating conditions, and switching characteristics. The datasheet also contains test circuit examples, performance graphs, and a section on restrictions for product use and safety considerations.
