BFR505 Frequently Asked Questions (FAQ)

  • The recommended operating voltage range for the BFR505 is 4.5V to 5.5V, although it can tolerate up to 7V for short periods.

  • To ensure proper biasing, connect the base of the transistor to a voltage divider network that sets the base voltage to around 1.4V to 1.6V, and use a current-limiting resistor in series with the collector to prevent excessive current.

  • The maximum collector current rating for the BFR505 is 100mA, but it's recommended to keep the current below 50mA for reliable operation and to prevent overheating.

  • Yes, the BFR505 can be used as a switch, but it's essential to ensure the base is properly driven to achieve a low saturation voltage (Vce(sat)) and to minimize power dissipation. A base current of around 1mA to 2mA is typically sufficient.

  • The BFR505 has a thermal resistance (Rth(j-a)) of around 200°C/W. To manage thermal issues, ensure good heat sinking, use a thermal pad or heat sink, and keep the ambient temperature below 50°C.
