BZX85B12-TR Frequently Asked Questions (FAQs)

  • The recommended land pattern for the BZX85B12-TR can be found in the Vishay Intertechnologies' application note 'Land Pattern Recommendations for Vishay SMD Diodes' (document number 28636).
  • For reflow soldering, ensure that the BZX85B12-TR is placed on a solder paste layer with a thickness of 0.1 mm to 0.2 mm. The recommended reflow profile is a peak temperature of 260°C with a dwell time of 20-30 seconds above 220°C.
  • The BZX85B12-TR has a moisture sensitivity level (MSL) of 1, which means it can be exposed to a maximum of 30°C/60% RH for 168 hours before reflow soldering.
  • Yes, the BZX85B12-TR is suitable for high-reliability applications. It is manufactured using a high-reliability process and is screened to ensure low defect rates. However, it is recommended to consult with Vishay Intertechnologies' application engineers to ensure that the device meets the specific requirements of your application.
  • The equivalent series resistance (ESR) of the BZX85B12-TR is not explicitly stated in the datasheet. However, it is typically in the range of 0.5 ohms to 1.5 ohms for a zener diode of this type. For more accurate information, please consult with Vishay Intertechnologies' application engineers.
