High-Voltage Optoisolator for Industrial, Transportation and Medical Applications

TT electronics Optoelectronics Business Unit announced that the OPI1268S has become the industry's only high-voltage opto-isolator to carry all four of the UL, VDE, ATEX/IECex and IP65 certifications for operation in harsh and potentially hazardous environments. Featuring 20KV isolation and <50ns propagation delay, the OPI1268S is ideal for metering equipment, transportation systems, hybrid vehicles, medical devices, and industrial control/safety systems.

The OPI1268S opto-isolator is based on a high-efficiency LED with a peak wavelength of 850nm, optically coupled to a photodiode that detects incoming modulated light and converts it to a proportionate current. The device features a high-gain linear amplifier that is temperature-, current-, and voltage-compensated, resulting in a highly stable digital output with a data transfer rate of 2Mbits/s and a typical propagation delay (tPHL-tPLH) of 50ns. Capable of isolating voltages up to 20kV, the OPI1268S also provides a voltage spike immunity of 30KV/µS dv/dt. As a result, the OPI1268S is unprecedented in protecting users, robotic interfaces and control circuits from high voltage.

Additional features include an input diode with a forward voltage of 1.8V (max) @IF = 20mA and a continuous forward current of 50mA. Reverse current is 100µA (max) @VR = 2.0V with reverse voltage of 3.0V. The output IC operates with 7V supply voltage with 40mW power dissipation. Operating temperature range is from -50°C to +100°C.

The OPI1268S is available now, supplied in a five-lead configuration measuring 27.94mm x 6.35mm x 8.89mm.
