BZX85B20-TR Frequently Asked Questions (FAQs)

  • The recommended land pattern for the BZX85B20-TR can be found in the Vishay Intertechnologies' application note AN10365, which provides guidelines for surface mount assembly of diodes and rectifiers.
  • To prevent thermal damage during soldering, it is recommended to follow the soldering profile recommended in the datasheet, and to use a soldering iron with a temperature of 260°C (500°F) or less. Additionally, the component should be exposed to the soldering iron for no more than 3 seconds.
  • The ESR of the BZX85B20-TR is not explicitly stated in the datasheet, but it can be estimated to be around 1-2 ohms based on the device's internal construction and similar devices from Vishay Intertechnologies.
  • The BZX85B20-TR is a general-purpose zener diode and is not optimized for high-frequency applications. It may not perform well above 100 kHz, and alternative devices such as the BZV55C series from Vishay Intertechnologies may be more suitable for high-frequency applications.
  • The MSL of the BZX85B20-TR is MSL1, which means it can be exposed to a maximum of 30°C/85% relative humidity for 168 hours without being damaged.
