1N938B Frequently Asked Questions (FAQ)

  • The recommended soldering temperature for the 1N938B is between 250°C to 260°C for a maximum of 10 seconds.

  • While the 1N938B is a general-purpose diode, it's not recommended for high-frequency switching applications due to its relatively high reverse recovery time (trr) of 3μs. A faster diode with a lower trr would be more suitable.

  • To prevent electrostatic discharge (ESD) damage, handle the 1N938B with an anti-static wrist strap or mat, and ensure that your workspace is ESD-protected. Avoid touching the device's pins or leads with your bare hands.

  • The maximum allowable voltage derating for the 1N938B is 80% of the rated voltage at high temperatures (above 25°C). This means that if the rated voltage is 1000V, the maximum allowable voltage at high temperatures would be 800V.

  • While it's technically possible to use multiple 1N938B diodes in parallel to increase current handling, it's not recommended due to potential mismatch and uneven current distribution between devices. Instead, consider using a single diode with a higher current rating.
