TLP798GA is a photocoupler manufactured by TOSHIBA. Its maximum off-state voltage is 400V, maximum on-state current is 150mA, maximum on-state resistance is 12 ohms, and maximum isolation voltage is 5000Vrms. The isolation thickness is 0.4mm.
The Toshiba TLP798GA is a bi-directional switch utilizing an aluminum gallium arsenide infrared emitting diode optically coupled to a photo-MOS FET. It is designed in a six-lead plastic DIP package (DIP6) to replace mechanical relays in various applications such as telecommunication, data acquisition, and measurement instrumentation.
The device features three connection modes (A, B, and C) with specific ratings for off-state voltage up to 400 V and isolation voltage of 5000 Vrms. Key specifications include a maximum forward current of 30 mA, an operating temperature range of -40°C to +85°C, and turn-on/off times under 1.0 ms.
