MMBT3904 Frequently Asked Questions (FAQ)
-
The MMBT3904 can operate safely between -55°C to 150°C, but the recommended operating temperature range is -40°C to 85°C for optimal performance.
-
To ensure the MMBT3904 is properly biased for saturation, the base-emitter voltage (VBE) should be around 0.7V, and the collector-emitter voltage (VCE) should be around 0.2V to 0.5V. The base current (IB) should be around 1/10th to 1/20th of the collector current (IC).
-
The MMBT3904 can handle a maximum collector current (IC) of 200mA and a maximum power dissipation (PD) of 625mW.
-
To protect the MMBT3904 from ESD, handle the device by the body, use an anti-static wrist strap or mat, and store the device in an anti-static bag or container.
-
Yes, the MMBT3904 can be used as a switch, but it's not recommended due to its relatively low current handling capacity and power dissipation. A more suitable transistor for switching applications would be a higher-power device like the 2N3904.
