ROHM recommends a PCB layout with a thermal pad connected to a large copper area on the bottom layer, and multiple vias to dissipate heat efficiently. A minimum of 2oz copper thickness is recommended.
To ensure the LED is driven within its SOA, calculate the maximum forward current (IF) and pulse width (tp) based on the application's requirements. Then, select a suitable resistor value for the current limiting resistor (R) using the formula: R = (VCC - VF) / IF, where VF is the forward voltage drop of the LED.
ROHM recommends storing the LTR18EZPFLR270 in a dry, cool place with a temperature range of 5°C to 30°C and humidity below 60%. Avoid exposing the device to direct sunlight, moisture, or extreme temperatures.
Yes, the LTR18EZPFLR270 is suitable for high-reliability applications. ROHM has implemented various quality control measures, including 100% inspection and burn-in testing, to ensure the device meets stringent reliability standards.
ROHM provides binning information for the LTR18EZPFLR270, which includes chromaticity and luminous intensity data. Use this information to select the appropriate bin for your application. Additionally, consider using optical simulation tools to optimize your design and ensure the desired optical performance.
