MMBT3904 Frequently Asked Questions (FAQ)
-
The MMBT3904 can operate safely between -55°C and 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 at least 1V. Additionally, 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 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 essential to ensure the transistor is fully saturated (VCE(sat) < 0.5V) to minimize power consumption and heat generation.
