SMP100MC-360 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  STMicroelectronics provides a recommended PCB layout in their application note AN4979, which includes guidelines for thermal vias, copper pours, and component placement to ensure optimal thermal performance.
• How do I select the correct input capacitor for the SMP100MC-360?
  The input capacitor selection depends on the input voltage, current, and frequency. A general guideline is to choose a capacitor with a voltage rating of at least 1.5 times the maximum input voltage, and a capacitance value between 10uF to 100uF. Additionally, consider the capacitor's ESR, ESL, and ripple current rating.
• What is the maximum allowed voltage drop across the internal resistance of the SMP100MC-360?
  The maximum allowed voltage drop across the internal resistance of the SMP100MC-360 is typically around 1V to 2V, depending on the specific application and operating conditions. Exceeding this limit may affect the device's reliability and performance.
• Can I use the SMP100MC-360 in a high-temperature environment?
  The SMP100MC-360 is rated for operation up to 150°C, but the device's performance and reliability may degrade at high temperatures. It's essential to consider the thermal management and derating factors when operating the device in high-temperature environments.
• How do I ensure electromagnetic compatibility (EMC) with the SMP100MC-360?
  To ensure EMC, follow proper PCB design and layout guidelines, use shielding and filtering components, and consider the device's radiated and conducted emissions. Additionally, perform EMC testing and certification according to relevant standards and regulations.
