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 of the collector current (IC).

  • The MMBT3904 can handle a maximum collector current (IC) of 200mA and a maximum peak current (ICM) of 400mA.

  • To protect the MMBT3904 from ESD, handle the device by the body or use an anti-static wrist strap, and store the device in an anti-static bag or container. Avoid touching the device's pins or leads.

  • Yes, the MMBT3904 can be used as a switch, but it's not recommended for high-frequency switching applications due to its relatively slow switching time (around 10-20ns). It's better suited for low-frequency switching or amplification applications.
