SMDJ22A - LITTELFUSE

SMDJ22A Frequently Asked Questions (FAQs)

• What is the recommended land pattern for SMDJ22A?
  The recommended land pattern for SMDJ22A is a rectangular pad with a minimum size of 2.5mm x 1.5mm, with a 0.5mm radius corner and a 0.3mm solder mask clearance.
• Can I use SMDJ22A in a high-temperature application?
  Yes, SMDJ22A is rated for operation up to 150°C, but it's recommended to derate the component's current rating by 1.5% per degree Celsius above 125°C to ensure reliable operation.
• How do I handle the SMDJ22A during assembly to prevent damage?
  Handle SMDJ22A by the body only, avoiding touching the leads or the glass passivation layer. Use a vacuum pickup or tweezers to handle the component, and avoid bending or flexing the leads during assembly.
• What is the recommended soldering profile for SMDJ22A?
  The recommended soldering profile for SMDJ22A is a peak temperature of 260°C, with a dwell time of 10-30 seconds above 220°C. Avoid using a soldering iron with a temperature above 300°C.
• Can I use SMDJ22A in a high-humidity environment?
  Yes, SMDJ22A is designed to operate in humid environments, but it's recommended to follow the manufacturer's guidelines for moisture sensitivity level (MSL) and to bake the components according to the MSL rating before assembly.
