DMMT3904-TP Frequently Asked Questions (FAQs)

• What is the recommended PCB footprint for the DMMT3904-TP?
  The recommended PCB footprint for the DMMT3904-TP is a standard SOT-23 package with a 0.95mm x 0.95mm pad size and a 0.5mm x 0.5mm thermal pad.
• How do I handle the thermal pad on the DMMT3904-TP?
  The thermal pad on the DMMT3904-TP should be connected to a copper plane on the PCB to improve heat dissipation. A thermal via or a thermal pad on the PCB is recommended to connect to the thermal pad on the device.
• What is the maximum operating temperature range for the DMMT3904-TP?
  The maximum operating temperature range for the DMMT3904-TP is -55°C to 150°C, but the device is typically specified for operation from -40°C to 125°C.
• How do I ensure the DMMT3904-TP is properly biased?
  The DMMT3904-TP requires a bias voltage of 5V to 30V, and the recommended bias current is 1mA to 10mA. The device should be biased through a current-limiting resistor to prevent overcurrent.
• What is the typical switching time for the DMMT3904-TP?
  The typical switching time for the DMMT3904-TP is around 10ns to 20ns, but this can vary depending on the specific application and operating conditions.
