SMDJ43A - LITTELFUSE

SMDJ43A Frequently Asked Questions (FAQs)

• What is the recommended land pattern for the SMDJ43A?
  The recommended land pattern for the SMDJ43A is a rectangular pad with a size of 2.5mm x 1.5mm, with a 0.5mm radius corner. The pad should be centered on the component and have a solder mask defined gap of 0.2mm.
• How do I handle the SMDJ43A during assembly to prevent damage?
  Handle the SMDJ43A by the body only, avoiding touching the leads or the glass passivation. Use an anti-static wrist strap or mat to prevent electrostatic discharge (ESD) damage. Avoid bending or flexing the leads, and do not use excessive force during assembly.
• What is the maximum allowable voltage for the SMDJ43A?
  The maximum allowable voltage for the SMDJ43A is 43V, as indicated in the part number. Exceeding this voltage may cause the device to fail or be damaged.
• Can I use the SMDJ43A in a high-temperature environment?
  The SMDJ43A is rated for operation up to 150°C. However, the device's performance and reliability may degrade at high temperatures. Consult the datasheet and application notes for specific guidance on high-temperature operation.
• How do I determine the correct orientation of the SMDJ43A during assembly?
  The SMDJ43A has a polarity mark on the package, which indicates the cathode (negative) lead. Ensure the polarity mark is aligned with the corresponding pad on the PCB to prevent incorrect assembly.
