RN2405(TE85L,F) - Toshiba

RN2405(TE85L,F) Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  Toshiba recommends a PCB layout with a thermal pad connected to a large copper area on the bottom layer, and multiple vias to dissipate heat. A minimum of 2oz copper thickness is recommended.
• How do I ensure reliable operation at high temperatures?
  Ensure proper heat sinking, use a thermally conductive material for the PCB, and consider using a heat sink or thermal interface material. Also, derate the power dissipation according to the temperature derating curve in the datasheet.
• What is the maximum allowed voltage for the input pins?
  The maximum allowed voltage for the input pins is 5.5V, which is the absolute maximum rating. However, for reliable operation, it is recommended to keep the input voltage below 5V.
• Can I use this device in a high-humidity environment?
  Yes, the RN2405 is designed to operate in a humid environment, but it's recommended to follow proper PCB design and assembly guidelines to prevent moisture-related issues. Consider using a moisture-resistant coating or conformal coating for added protection.
• How do I handle ESD protection for this device?
  Toshiba recommends using ESD protection devices, such as TVS diodes or ESD arrays, on the input and output pins to prevent damage from electrostatic discharge. Follow proper handling and storage procedures to prevent ESD damage.
