FMMT491TC Frequently Asked Questions (FAQ)
-
A thermal pad on the bottom of the package should be connected to a large copper area on the PCB to dissipate heat efficiently. A minimum of 2oz copper thickness is recommended.
-
The FMMT491TC requires a bias voltage of 5V to 15V, and the recommended bias current is 1mA to 10mA. Ensure the bias circuit is stable and noise-free to prevent oscillations.
-
The maximum power dissipation for the FMMT491TC is 1.5W. Ensure the device is properly heat-sinked and the ambient temperature is within the recommended range to prevent overheating.
-
Yes, the FMMT491TC can be used in switching applications, but ensure the switching frequency is within the recommended range (up to 100kHz) and the device is properly biased to prevent oscillations.
-
Handle the device with ESD-protective equipment, and ensure the PCB has ESD-protection circuitry, such as TVS diodes or ESD-protection arrays, to prevent damage from static electricity.
