4N35 Frequently Asked Questions (FAQs)

  • The 4N35 can operate safely between -40°C to 100°C, but the optimal operating temperature range is between 0°C to 70°C for reliable performance.
  • To ensure proper biasing, connect the anode of the LED to a voltage source (e.g., VCC) through a current-limiting resistor (e.g., 1 kΩ). The recommended forward current is 10-20 mA.
  • The typical CTR of the 4N35 is around 100%, but it can vary between 50% to 200% depending on the specific device and operating conditions.
  • The 4N35 is not suitable for high-frequency applications (>1 MHz) due to its limited bandwidth. For high-frequency applications, consider using a faster optocoupler like the 6N137 or 6N138.
  • To protect the 4N35 from EOS, use a voltage limiter or a transient voltage suppressor (TVS) diode in parallel with the optocoupler. This will help absorb voltage spikes and prevent damage.
