NR131S Frequently Asked Questions (FAQ)

  • A thermal pad on the bottom of the package should be connected to a large copper area on the PCB to dissipate heat efficiently. A minimum of 2oz copper thickness is recommended.

  • Ensure that the device is operated within the recommended temperature range (up to 150°C). Use a heat sink or thermal interface material to maintain a safe junction temperature.

  • The maximum allowed voltage on the input pins is 20V, but it's recommended to keep it below 15V to ensure reliable operation and prevent damage to the device.

  • Yes, the NR131S is suitable for high-frequency switching applications up to 100 kHz. However, ensure that the device is properly bypassed and decoupled to minimize electromagnetic interference (EMI).

  • Use a fuse or a current-limiting resistor in series with the input to prevent overcurrent. Add a voltage regulator or a zener diode to protect against overvoltage.
