The maximum operating temperature range for the 2N3904BU is -55°C to 150°C.
Yes, the 2N3904BU can be used as a switch, but it's not recommended for high-frequency switching applications due to its relatively low transition frequency (ft) of 250 MHz.
To ensure proper biasing, set the base voltage (VBE) to around 0.7V and the collector-emitter voltage (VCE) to around 1V to 5V, depending on the specific application requirements.
The maximum collector current (IC) rating for the 2N3904BU is 200 mA.
No, the 2N3904BU is not suitable for high-voltage applications, as its maximum collector-emitter voltage (VCE) rating is 40V.
