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 125°C.

  • To ensure proper biasing, the base-emitter voltage (VBE) should be around 0.7V, and the collector-emitter voltage (VCE) should be around 1V to 2V. The base current should be limited to prevent overheating.

  • The maximum collector current (IC) rating for the MMBT3904 is 200mA, and the maximum peak current rating is 300mA.

  • To protect the MMBT3904 from ESD, handle the device with an anti-static wrist strap or mat, and avoid touching the pins or leads. Use ESD-sensitive handling procedures and store the devices in anti-static packaging.

  • Yes, the MMBT3904 can be used in switching applications, but it's essential to ensure the device is properly biased and the switching frequency is within the recommended range (up to 100 kHz).
