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 should be around 1/10th of the collector current.

  • The maximum collector current rating for the MMBT3904 is 200mA. Exceeding this rating can cause the transistor to overheat and potentially fail.

  • Yes, the MMBT3904 can be used as a switch. However, it's essential to ensure the transistor is properly biased and the collector-emitter voltage is low enough to minimize power dissipation.

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