KP40101B

Photovoltaic Output

OptocouplerTransistor OutputHigh VoltageIsolation

The KP40101B is a high-reliability, transistor-output optocoupler designed for high-voltage isolation and efficient signal transmission in industrial and power applications.

Best for

  • Industrial automation
  • Power supply interface
  • Signal isolation

Avoid if

  • Applications requiring extremely high-speed switching (kHz range is limited)
  • Space-constrained designs where SMD is mandatory (this is a DIP package)

Check before use

  • Thermal derating at high ambient temperatures
  • CTR variation across different current levels
