Miniature photocoupler combines high switching speed with 3.3V low power operation

Toshiba’s new photocoupler integrates a GaAlAs infrared LED and a high-gain, high-speed photodetector within a surface mount MFSOP6 package that measures just 4.4mm x 3.6mm x 2.5mm. Maximum propagation delay is just 60ns, leading to typical switching speeds of 20MHz.

Operating with a nominal power supply voltage of 3.3V, the TLP2066 has a maximum current consumption of just 5mA. The photocoupler is configured in an inverter logic (totempole output) format and provides an isolation voltage rated at 3750Vrms. An internal shield ensures a high common mode transient immunity of 15kV/µs (min).

Designed to comply with all international safety approvals, the TLP2066 offers guaranteed performance at temperatures ranging from -40ºC to 100 ºC.
