6-pin SDIP optocouplers focus on space constrained industrial applications

December 17, 2015 // By Paul Buckley
Everlight Electronics has introduced two single channel 6-pin SDIP 1Mbit/sec and 10 Mbit/sec transistor output optocouplers. With half the dimensions of comparable 8-Pin 6N13X devices, they are both suited for space constrained industrial applications.

Both ELS511 and ELS611 are SMD devices in a small outline 6-pin SDIP package. The ELS511 series devices each 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 increase the speed by several orders of magnitude over conventional phototransistor couplers by reducing the base-collector capacitance of the input transistor. The ELS611 series devices consist of an infrared emitting diode optically coupled to a high speed integrated photo detector logic gate with a storable output.

Their dimensions of 9.7 x 4.58 x 3.38 mm, half of those of a 6N13X series (8-pin), greatly eases the use in designs with limited PCB area to make them suitable for space constrained industrial applications such as high speed ground isolation.
