Everlight has announced the introduction of two new single-channel optocouplers intended for use in industrial applications.

The 1Mbit/s ELS511 and 10Mbits/s ELS611 are housed in a small 6-pin SOP package measuring 6.8mm x 4.6mm. The devices help users to save PCB space, and are ideal when implementing a size-reduction design.

The ELS511 optocouplers consist of an infrared emitting diode, optically coupled to a high speed photo-detector transistor. A separate connection for the photodiode bias and output-transistor collector increases the speed by several orders of magnitude compared to conventional phototransistor couplers by reducing the base-collector capacitance of the input transistor.

• 5,000Vrms isolation voltage between input and output
• Guaranteed performance from 0°C to 70°C
• Operating temperature range: -55°C to 100°C
