VLDK1235R - Vishay

VLDK1235R Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance of VLDK1235R?
  A symmetrical layout with a central ground plane and minimal track lengths is recommended. Keep the input and output tracks separate and avoid crossing them to minimize noise and EMI.
• How do I ensure the reliability of the VLDK1235R in high-temperature applications?
  Follow the recommended derating curves for temperature and ensure proper thermal management, such as using a heat sink or thermal interface material. Also, consider using a thermally conductive PCB material and ensuring good airflow around the component.
• What is the maximum allowed voltage transient for VLDK1235R?
  The maximum allowed voltage transient for VLDK1235R is 10% above the maximum rated voltage (35V) for a duration of 100ms. Exceeding this may cause damage to the component.
• Can I use VLDK1235R in a switching regulator application?
  Yes, VLDK1235R can be used in switching regulator applications, but ensure that the switching frequency is within the recommended range (typically < 500 kHz) and that the component is properly bypassed with capacitors to minimize noise and ringing.
• How do I handle ESD protection for VLDK1235R during handling and assembly?
  Follow standard ESD handling procedures, such as using an ESD wrist strap, mat, or workstation, and ensure that the component is stored in an ESD-protective package. During assembly, use ESD-protective tools and avoid touching the component's pins.
