东芝电子元件及存储装置株式会社(简称“东芝”)推出了4通道晶体管输出光耦(以下简称为“晶体管耦合器”)“TLP294-4”和“TLP295-4”,他们标准化了LED的输入阀值电压并采用SO16封装。
TLP294-4为交流输入型,TLP295-4为直流输入型。与东芝当前的晶体管耦合器[1]相比,这两款产品集成了一个用于晶体管基极存储电荷的放电电阻器,因此传输延迟时间更短。现有的晶体管耦合器已用于通信速度高达10kbps 左右的应用,而新产品支持10kbps至20kbps,因此适用于可编程逻辑控制器和逆变器等FA设备以及绝缘通信接口应用。这类4通道产品可进行高密度安装。
绝缘性能方面,此类产品的最小爬电距离为5mm,最小隔离电压为3.75kVrms,并通过UL1577、EN 60747-5-5等国际安全标准认证。因此,它们也适用于具有高绝缘性能要求的应用。
