LTL-155EHA - Lite-On

LTL-155EHA Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  A 2-layer PCB with a solid ground plane on the bottom layer and a thermal relief pattern on the top layer is recommended. This helps to dissipate heat efficiently and reduces thermal resistance.
• How do I ensure reliable operation in high-temperature environments?
  Ensure proper heat sinking, use a thermal interface material (TIM) with a thermal conductivity of at least 1 W/m-K, and consider using a heat sink with a thermal resistance of less than 10°C/W.
• What is the maximum allowable voltage derating for this LED?
  The maximum allowable voltage derating is 10% of the maximum rated voltage. Exceeding this may reduce the LED's lifespan or cause premature failure.
• Can I use this LED in a dimmable circuit?
  Yes, but ensure the dimming frequency is above 100 Hz to avoid flicker. Also, use a dimming method that does not exceed the maximum rated current or voltage.
• How do I handle ESD protection for this LED?
  Use a human body model (HBM) ESD protection device with a minimum rating of 2 kV. Ensure the protection device is connected between the LED's anode and cathode.
