Hero Electronics Ltd. has introduced a low-profile SMD optocoupler manufactured by Bedford Opto Technology. The OPI1000L is suitable for applications such as metering and instrumentation in hazardous environments that require signal isolation up to 10 kV. Its infrared emitter couples to a silicon phototransistor that provides a minimum current transfer ratio of 40% at 1 mA input current. The device can be gain-selected for higher transfer ratios to meet application requirements. The optocoupler's output transistor has a breakdown level of 35 V and is capable of 165 mW of dissipation over a temperature range of -25 to +100 °C.
