6N138 Frequently Asked Questions (FAQs)

  • The maximum allowable voltage that can be applied to the input pins is 5V, as exceeding this voltage can cause damage to the internal LED.
  • To ensure reliable operation in high-temperature environments, it's essential to derate the device's current handling capability according to the temperature derating curve provided in the datasheet.
  • The recommended input current for the 6N138 is typically in the range of 1-10mA, depending on the specific application requirements and the desired output current transfer ratio.
  • While the 6N138 can be used for high-frequency applications, its bandwidth is limited to around 10kHz. For higher frequency applications, consider using a faster optocoupler like the 6N139 or 6N140.
  • To minimize EMI, use proper PCB layout techniques, such as separating the input and output circuits, using a ground plane, and adding shielding if necessary.
