SMBJ22D-M3/H - Vishay

SMBJ22D-M3/H Frequently Asked Questions (FAQs)

• What is the recommended footprint and land pattern for the SMBJ22D-M3/H?
  The recommended footprint and land pattern for the SMBJ22D-M3/H can be found in the Vishay Intertechnologies' application note AN10365, which provides guidelines for surface-mount assembly of SMBJ devices.
• How do I handle the SMBJ22D-M3/H during assembly to prevent damage?
  To prevent damage, handle the SMBJ22D-M3/H by the body only, avoiding touching the leads or the glass passivation. Use anti-static wrist straps, mats, or other ESD protection methods to prevent electrostatic discharge damage.
• What is the maximum allowable soldering temperature and time for the SMBJ22D-M3/H?
  The maximum allowable soldering temperature for the SMBJ22D-M3/H is 260°C (500°F) for 10 seconds, with a maximum of 3 reflows. Soldering conditions should be in accordance with J-STD-020D.
• Can the SMBJ22D-M3/H be used in high-reliability or aerospace applications?
  The SMBJ22D-M3/H is a commercial-grade device, but Vishay Intertechnologies offers a high-reliability version, the SMBJ22D-M3/HF, which is screened to NASA-level standards and is suitable for aerospace and other high-reliability applications.
• How do I determine the correct orientation of the SMBJ22D-M3/H during assembly?
  The SMBJ22D-M3/H has a polarity mark on the body, which indicates the cathode (K) terminal. The cathode terminal should be oriented according to the PCB layout and design requirements.
