DRDNB26W-7 datasheet by Diodes Incorporated

DRDNB26W-7 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  Diodes Incorporated recommends a PCB layout with a solid ground plane and a thermal relief pattern under the device to ensure optimal thermal performance. A minimum of 2 oz copper thickness is recommended.
• How do I ensure reliable operation at high temperatures?
  To ensure reliable operation at high temperatures, it's essential to follow the recommended derating curves for voltage and current, and to ensure proper heat sinking and thermal management. Additionally, consider using a thermistor or thermal sensor to monitor the device temperature.
• What is the maximum allowed voltage transient for this device?
  The DRDNB26W-7 can withstand voltage transients up to 40V for a duration of 100ms, as specified in the datasheet. However, it's recommended to use a TVS diode or other protection devices to ensure the device is protected from voltage spikes and transients.
• Can I use this device in a high-frequency switching application?
  While the DRDNB26W-7 is suitable for high-frequency switching applications, it's essential to consider the device's switching characteristics, such as rise and fall times, and ensure that the application's switching frequency is within the device's recommended operating range.
• How do I select the correct input capacitor value for this device?
  The input capacitor value depends on the input voltage, output voltage, and output current requirements. A general rule of thumb is to use a capacitor with a value between 1uF to 10uF, with a voltage rating that exceeds the maximum input voltage. However, it's recommended to consult the datasheet and application notes for specific guidance.
