Description

The 6N138 and 6N139 devices each consists of an infrared emitting diode, optically coupled to a high gain split Darlington photo detector. They provide extremely high current transfer ratio between input and output, with access to a base terminal to adjust the gain bandwidth.

These devices are packaged in an 8-pin DIP package and available in wide-lead spacing and SMD options.

Features:

• High current transfer ratio– 2000 typical

• High isolation voltage between input and output (Viso=5000 Vrms )

• Guaranteed performance from 0°C to 70°C

• Pb free and RoHS compliant.

• UL approved (No. 214129)

• VDE approved (No. 132249)

• SEMKO approved

• NEMKO approved

• DEMKO approved

• FIMKO approved

• CSA approved (No. 2037145)

Applications

• Digital logic ground isolation

• RS-232C line receiver

• Low input current line receiver

• Microprocessor bus isolation

• Current loop receiver

6N138属于隔离器 > 光隔离器 - 晶体管，光电输出。亿光电子工业股份有限公司制造生产的6N138光隔离器 - 晶体管，光电输出晶体管或光电输出光隔离器通常出于安全或功能性原因，使用光来跨过电绝缘层进行信息传输。与其他光隔离器类型的区别在于，它们使用简单的光电晶体管或光伏电池（太阳能电池）作为输出设备。这些器件的输出不需要外部电源即可运行，并且具有模拟特性，因此可用于在无法实现电连接的电路之间传输模拟信息。
