Ultra-compact photocoupler delivers guaranteed, high-speed switching performance up to 125°C
Toshiba Electronics Europe (TEE) has launched an ultra-compact, high-speed inverter-type photocoupler that features guaranteed extended temperature performance while complying with the reinforced isolation class requirements of international safety standards.
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.
