The Toshiba TLP633 and TLP634 are solid‑state relay optocouplers that combine a gallium arsenide infrared emitting diode with a photo‑transistor in a six‑lead DIP package. They are intended for office machines, household equipment and switching power supplies.
The devices provide a collector‑emitter voltage rating of 55 V, isolation voltage up to 4000 Vrms, forward current of 40 mA and power dissipation of 150 mW. Recommended supply voltage is 5–24 V and they operate from –55 °C to 150 °C storage temperature.
