The TLP708 is ideal for home appliances as well as induction heating equipment, factory automation and other industrial designs where operation under extreme ambient temperatures and high levels of isolation is required. Performance is guaranteed at temperatures from -40°C to 125°C.
Comprising a GaAlAs LED that is optically coupled to an integrated, high-gain, high-speed photodetector, the TLP708 is supplied in a 6-pin SDIP (shrink DIP) package requiring just half the board mounting area of an equivalent 8-pin DIP device. Despite its small size, the photocoupler has a minimum isolation voltage rating of 5000Vrms.
Toshiba’s new photocoupler operates with a maximum switching time of just 75ns, allowing it to support typical data transfer rates of 15Mbit/s. The integrated photodetector has an open-collector output stage and an internal Faraday shield that provides a guaranteed common-mode transient immunity of ±15kV/µs.
The TLP708 has dimensions of just 9.7mm x 4.6mm x 4.0mm. As well as the standard device Toshiba also offers a version with extended creepage and clearance distances that has a board mounting footprint of 11.7mm x 4.6mm.
