1N4935 Frequently Asked Questions (FAQs)

  • The recommended mounting pad layout for the 1N4935 is a rectangular pad with a minimum size of 2.5 mm x 1.5 mm, with a 0.5 mm x 0.5 mm thermal relief pad in the center. This layout helps to ensure good thermal conductivity and reduces the risk of thermal damage.
  • Yes, the 1N4935 can be used in a switching power supply, but it's essential to ensure that the diode is properly snubbed to prevent voltage spikes and ringing. A snubber circuit can be added to reduce the voltage stress on the diode and prevent premature failure.
  • The maximum allowable case temperature for the 1N4935 is 150°C. Exceeding this temperature can reduce the diode's reliability and lifespan. It's essential to ensure that the diode is properly heat-sinked and that the ambient temperature is within the recommended operating range.
  • The 1N4935 is not suitable for high-frequency applications above 1 MHz due to its relatively high reverse recovery time (trr) of 3 μs. For high-frequency applications, a faster diode with a lower trr should be used.
  • The 1N4935 has a maximum repetitive peak reverse voltage (Vrrm) of 600 V, making it suitable for use in high-voltage applications up to 600 V. However, it's essential to ensure that the diode is properly protected against voltage transients and spikes.
