The Toshiba TLP633 and TLP634 are solid‑state relays 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, and are UL‑ and VDE‑approved for high‑EMI environments.
The document provides maximum ratings, detailed electrical and isolation characteristics, switching performance data, and recommended operating conditions, including supply voltage, temperature limits, and pin configurations.
