The Toshiba TLP202A consists of a gallium arsenide infrared emitting diode optically coupled to a photo-MOSFET in an 8-pin SOP package. This photorelay has higher output current rating than phototransistor-type photocoupler; hence, it is suitable for use as On/Off �� control for high current.
The TLP202A is a gallium‑arsenide infrared emitting diode optically coupled to a photo‑MOSFET in an 8‑pin SOP package. It offers a higher output current rating than phototransistor‑type photocouplers, making it suitable for on/off control of high‑current loads.
The document lists maximum ratings, recommended operating conditions, detailed electrical and isolation characteristics, switching times, and restrictions on product use, helping designers integrate the device safely into electronic applications.
